FORT DOOM:
LEFT BEHIND
A one-man-army run-and-gun where a time-displaced sergeant purges future-tech impostors from five Army bases. Contra energy, motor-pool humor.
A retro run-and-gun side-scroller with a military-comedy heart. A time-travel experiment on a network of Army bases tears a hole in the timeline, and future-tech replicants slip through and quietly take over each installation from the inside. Same uniforms, same haircuts, same complaints about the chow hall. Only one man can tell the difference.
The Pitch
Think Contra by way of an Army motor pool: run, gun, jump, crouch, and fight through Fort Polk's swamp, Fort Sill's artillery range, Fort Drum's frozen tundra, and beyond. Dodge platform snipers, aerial bombing runs, and boss-tier "prime replicants," while grabbing powerups airdropped by supply choppers.
- Sgt. Max "SNAFU" Stone · the only man who can spot the impostors, because he is from the future himself. No backup, no briefing, nobody who believes him.
- Five occupied bases · take them back one fort at a time, each a distinct theater with its own hazards.
- Airdropped powerups · the MRE that heals, the Reflective Belt that makes you invincible, the Safety Brief that freezes the whole enemy squad for a mandatory stand-down.
- Prime replicants · boss-tier impostors that anchor each fort.
Where It Actually Is
The honest version. This is a real playable prototype, not a mockup or a pitch deck. ~62% to a shippable v1.0, and the split is what matters:
What works now
- Engine essentially done (~95%): movement, shooting, enemy AI with a real state machine, boss fights, platforms
- Mobile touch controls with a twin-stick layout, built and stable
- Art pipeline solid (~90%): hand-painted or procedurally generated, renders identically every build
- The full five-fort campaign runs end to end
What is coming
- Unique movesets for the later bosses
- Sound design (none yet)
- Custom art for the final two forts
- More of the planned powerups
- Store-packaging (a pipeline already proven on prior releases)
The remaining ~38% is content breadth and ship-prep, not unknowns. It is a real runway, but it is known work, not research. For an in-development project, that is a strong place to be: there is an actual playable thing behind the pitch.

Tech & Craft Notes
Built in Godot 4, targeting both mobile and desktop. The enemy AI runs on a real state machine rather than scripted patterns, which is what makes the later-fort difficulty curve expressible as behavior rather than just more bullets. The procedural art approach keeps every build visually consistent without a growing pile of hand-drawn assets to maintain.
Framing note: this is called a playable prototype on purpose, not a demo or a beta. Demo implies polished-but-short; beta implies feature-complete-but-buggy. Prototype is exactly true: the systems work, the fun is provable, the content and polish are still filling in.
