Mega Defense - Staged Core Development with Monthly Competitive Seasons

💡 SIP: Ideas All Ideas
1

Hello Sandbox DAO community,

I’m proposing Mega Defense V2: Vanguard, a competitive action game built around a single scalable core, designed for fast delivery, strong replayability, and long-term competitive engagement within The Sandbox ecosystem.

This SIP idea focuses on delivering one complete, feature-ready game, then extending it through short, high-intensity monthly seasons with score-based rewards, rather than creating multiple short-lived experiences.

Mega Defense: No Escape is the first playable prototype of the Mega Defense

concept and is already live in The Sandbox Draft Gallery.

This version was built to validate the core gameplay loop and combat feel before scaling into Mega Defense V2.

P.s its only on the draft gallery for now, as it was provided as a game for the Retro game jam “

Prototype Scope

  • 1 land

  • Single-sided enemy attacks

  • 4 weapons

  • 12 waves (levels)

The prototype focuses on skill-based shooting, enemy pressure, and survival, intentionally keeping the scope limited to ensure stability and fast iteration. Feedback and playtesting from this version directly inform the expanded design proposed in Mega Defense V2, including multi-directional combat, increased weapon variety, deeper enemy systems, and seasonal competition.

This playable version demonstrates the foundation on which the full seasonal game will be built.
I already got some great reviews from players

Project Overview

Mega Defense V2 is a player-centered, 360-degree action shooter focused on skill-based shooting, aiming accuracy, and survival.

Instead of fragmenting development across multiple games, this proposal invests in a durable core game that can support repeated competitive seasons without rebuilding the foundation.

Key Gameplay Pillars

  • Skill-based shooting mechanics focused on accuracy and player skill

  • Clear, readable difficulty progression

  • High replayability through score optimization

  • Competitive leaderboards and seasonal rewards

Development Structure (Single Phase, 3 Stages + Testing - 8 Weeks Total)

Development is structured as one phase, divided into three funded stages, followed by a dedicated testing period.
Funding is released progressively, based on milestone approval.

Stage 1 - Core Combat & Systems (Weeks 1–4)

Starting Budget: $8,000 (released at project start)

  • Core combat mechanics

  • Full 360-degree combat design featuring multiple weapon classes:

    • Rifles

    • Heavy machine guns

    • Sniper rifles

    • Hand cannons

    • Flares

    • Grenades

  • 2x2 land layout with the player positioned at the center

  • Basic save and scoring systems

  • Night Attacks- Flare system.

Deliverable:
Playable core combat prototype demonstrating the full gameplay foundation.

Stage 2 - Content & Difficulty Scaling (Weeks 5–6)

Budget: $8,000 (released after Stage 2 approval)

  • 100–5,00+ unique levels

  • Structured, readable difficulty curves

  • 30+ enemy variations with scalable behaviors

  • Initial balance and pacing pass

Deliverable:
Content-complete game with scalable difficulty and enemy variety.

:small_blue_diamond: Funding note:
The second $8,000 tranche is released only after Stage 2 deliverables are reviewed and approved.

Stage 3 -Polish & Season Preparation (Week 7)

Budget: $6,000 (released after testing approval)

  • Leaderboards and score validation

  • Anti-exploit logic

  • Performance optimization

  • Season-ready release build

Deliverable:
Feature-complete, season-ready game.

Week 8 -Testing & Validation (No Additional Budget)

  • Full gameplay testing

  • Difficulty and balance verification

  • Performance and stability checks

  • Final bug fixes before Season 1

Deliverable:
Validated release build ready for competitive seasons.

:small_blue_diamond: Funding note:
The final $6,000 tranche is released only after the testing period is completed and approved.

Total Development Budget

$24,000 USD (one-time, capped)

  • $8,000 starting budget (Stage 1)

  • $8,000 released after Stage 2 approval

  • $6,000 released after testing approval

  • $2,000 allocated for creator seasonal support ($500 × 4 seasons)

Seasonal Competition Model

  • Monthly competitive seasons

  • 3–4 seasons total after launch

  • Seasons begin immediately after development completion

  • Score-based leaderboards reset every season

  • The Sandbox DAO retains full authority to adjust the seasonal rewards pool, modify prize amounts, or approve additional seasons based on performance results and community feedback

Seasonal Rewards (Players)

  • 10,000 SAND per season

  • Distributed to top-performing players only

  • Transparent and auditable distribution

  • Rewards are capped per season

Creator Seasonal Support (Not Development Funding)

  • $500 per completed season

  • Covers live maintenance, minor balance updates, and seasonal reporting

  • Fixed amount, no scaling or inflation

Why Monthly Seasons?

  • Creates urgency and frequent engagement

  • Faster feedback and balanced iteration

  • Clear evaluation points for DAO review

  • Strong fit for competitive, arcade-style gameplay

Expected Impact

  • Fast delivery of a complete competitive game

  • Strong replayability and player retention

  • Clear ROI on DAO funding through reusable systems

  • A repeatable seasonal game model for future SIPs

Mega Defense V2 aims to demonstrate how DAO-funded projects can:

  • Ship fast

  • Maintain accountability through milestones

  • Reward skill-based play

  • Deliver sustained value to The Sandbox ecosystem

Finally, I’d like to add some clarifications based on player feedback and my own development notes.

Regarding the shooting system, there are certain technical limitations when working within The Sandbox. To ensure stable performance and avoid runtime errors, the player is intentionally fixed in position with no movement. This design choice reduces player-positioning variables and allows the combat system to function reliably alongside increasingly complex enemy behaviors.

Some issues observed in the Draft Gallery version are Draft-only limitations. For example, certain weapons-such as the sniper rifle-appear less effective due to Draft Gallery-specific bugs. To prevent instability, I temporarily disabled some sniper-related wave logic in this version. These limitations are not present in the client version and will be fully addressed in the final release.

Mega Defense: No Escape was submitted as a Game Jam project. It serves as a proof-of-concept to validate the core gameplay loop, shooting mechanics, and enemy pressure system. This prototype confirms that the core idea works as intended.

Behind this prototype is over two years of work focused on building a modular map system capable of supporting 1,000+ levels, even 10000+ Levels within a single game. This was not fully achievable until the final save-game system was completed. While the save progression is now finalized, the modular mapping system has been in place for a long time and has already applied.

Thanks to this system:

  • Loading specific levels for testing is fast and efficient

  • Content scaling is stable

  • Performance remains consistent even at high-level counts

The proposed 500+ levels will be unique in gameplay feel. The system is based on modular RNG mapping, meaning each playthrough can generate different enemy combinations and patterns. Even when difficulty remains similar, enemy compositions and encounters vary, ensuring high replayability.

If you’ve played the prototype, you may notice that runs feel familiar in difficulty—but different in execution. This is intentional and central to the long-term design.

The game looks fun with nice mecanics for sure.
Since the game is build in beta yet, maybe the budget for this part could be less.

Or it’s the price you ask for selling the game to the DAO ?

I like the idea but I don’t like the idea that the DAO fund games that DAO don’t own.

Maybe we need to have a DAO library with all game fund by the dao. Since exp are not nft but lands are, the game should be publish on the DAO lands.

Played the prototype and had a lot of fun with it! The core loop feels solid, and the seasonal format makes sense for replayability. Funding one strong, reusable game that can be supported over multiple seasons feels like a good way for the DAO to get lasting value from a single experience. Curious to see how V2 shapes up, keep up the good work! :smiley:

Giving the strong potential and the super good impression I got for my first gameplays on the prototype, I can only be positive for funding the development of this game!

2 Questions :

  • How much seasons do you plan on running?
  • Is the organization of the seasons covered by the SIP?

Thanks @Alesoir for your question,
In the SIP idea, a 10,000 SAND prize pool was presented as an initial reference proposal to illustrate the scale of competitive incentives.

However, this amount is not finalized nor strictly enforced by the SIP. The final prize allocation, distribution per season, and any adjustments are intended to be subject to DAO governance and can be modified based on season structure, participation, and overall performance after launch.

In short, 10,000 SAND represents a proposed baseline, not a fixed commitment.

Thanks @sebga

If the DAO supports this project, the game will be fully owned by the DAO.

The final version of the game will be completely rebuilt based on the existing proof of concept currently available in the Draft Gallery. While the 1×1 Draft Gallery version proves the core gameplay loop, it is intentionally constrained and cannot support the full scale of the project. It represents a fully working core gameplay prototype, but is limited by space and system constraints and does not reflect the full vision.

Specifically, the Draft Gallery version:

  • Has no progression or leveling system, with 100–500+ levels planned for the full release.

  • Is limited to 12 waves, with only 5–7 enemy variants, rather than the 30+ variants proposed for the full game.

  • Has no save system to preserve scores and progression, which is required for long-term replayability.

  • Does not include night mode or sniper-focused waves.

  • Offers only 4 weapons, with no upgrade paths.

  • Has no shop system, which is planned to introduce strategic build choices.

  • Includes no assistant systems, such as airstrikes or flares.

These limitations prevent the implementation of the required variation, scalability, and long-term control over a large number of levels.

As a result, there is no remaining room for meaningful expansion within the Draft Gallery version. Achieving the full vision requires a new, scalable build, while preserving and expanding upon the validated core gameplay demonstrated in the proof of concept.

Feel free to ask about anything. I’m happy to clarify any details and make sure everything is as clear as possible.

I fully support this idea! I love the creative use of various modes despite the limitations Game Maker still poses to builders. If there is anyone who can pull this off, it’s @ixura , who has created some of the most advanced game mechanics in GM existing today.

We are also working with him on Magic Realms game modes, and he is a very reliable and knowledgeable creator. I think we desperately need more of these minigames on the platform that hook instantly and have high replayability and competitive setups implemented to bring players back over and over again.

Thank you for all the details. I support your initiative.

I’m just curious about the game’s stability once you add 100–500 levels and 30+ wave variants. I hope GM & Client can support that.

That said, I do support the initiative — it’s good to have a game in the DAO library that is owned by the DAO.

+1 for the shop you’re planning to add.

The project seems well thought out.

Thanks @sebga for your support

This is where modular level design becomes a foundational pillar of the experience. By driving the system through scalable variables and argumented logic, the game can organically generate over 100,000 truly unique levels.

Each level preserves the intended difficulty profile while delivering a fundamentally different gameplay approach. Even after 1,000+ playthroughs, players will never face the same enemy compositions, spatial arrangements, or encounter flows twice.

Progression is structured across clearly defined difficulty tiers-from Tier 1 to Tier 10-ensuring balance, mastery, and long-term engagement, while the underlying systems continuously evolve enemy variants, environments, and tactical challenges.

The result is a living, replayable experience where difficulty remains consistent, but the journey is always new
I have already validated this same Logical approach in a resource management experience, Tortuga, where it proved to be both stable and performant. Even when running on an older version of the GameMaker client, the system operated efficiently with no measurable performance impact.

Yes, this will make players eager to restart the journey again and again, experimenting with different approaches to maximize strategic depth and survive as long as possible. Even with an option to reset upgrades while preserving level progression, the system enables multiple strategic paths, significantly increasing replayability

I think this is a great idea. I would love playing and would fully support this. I have read @ixura ‘s responses and his answers are fair and I believe him to be MORE than competent and up to the task. After working in The Sandbox Game over the years, I have seen what he can do over time and his skills as a game dev are amazing. I believe without a doubt he would deliver a great product for the dao and a fun game and play experience for users.

10/10 here.

Thanks everyone for your support I really appreciate it.
Please feel free to ask questions or suggest any additional points that could be beneficial here. I’m very open to suggestions.
@Lanzer, I’d really value your thoughts your opinion matters a lot.
@theKuntaMC, what do you think is the best way to move forward?
I also feel we need more feedback from DAO members and delegates. Since I’m not allowed to tag delegates myself, could you help with that .

Thank you, @Lanzer . My objective is to build the best possible game by fully leveraging the capabilities of ** SANDBOX Game Maker**.

This project is not intended to compete with other Sandbox experiences. Instead, it is designed to compete with games developed using other game engines, placing the player experience at the center of every design decision.

The goal is to deliver a polished, engaging, and highly enjoyable game that prioritizes fun, strong gameplay, and replayability, standing confidently alongside titles built with any engine.
