Hordes of monsters behind you and 6 inches of reinforced steel between you and every step closer to freedom.

Every door between you and escape is secured with the latest in human-detecting minigame technology. Put your guns and gray matter to the test alone or with up to four friends.

PROTOTYPE

Project Upsilon is an untitled co-op horde shooter I'm currently prototyping for a future commercial release. This is just a thin slice of the gameplay and everything is a placeholder subject to change but I'd love to hear your feedback on the direction!

Note: The multiplayer server for this prototype will only be available until Jan 12th, 2026. Future opportunities to test multiplayer will be announced later.

Played the game? Let me know what you thought of it by taking a quick survey.

OBJECTIVE

You're faced with an unending horde of monsters with an ever decreasing magazine. To escape, you must override each exit door in you way by completing increasingly difficult minigames.

Each door's minigame can be played by multiple players at once so it's up to you whether to stand guard or help unblock your exit. But be warned, failing a minigame will temporarily seal the door and you'll have to wait for it to unlock before trying again.

Along the way, you may find additional doors which unlock armories to refill your team's ammo. Downed enemies may also drop ammo packs for a single player.

Beware maintenance hatches as these will quickly burst open once crossed starting a countdown for more monsters to spawn from them as well.

TEXT MINIGAME

Enter the text shown on screen to continue. The number of characters required is displayed as white underscores. Use the virtual keypad to enter characters, press OK to submit, or < to backspace.

The challenge text is randomly generated. While unlikely, any words or names it may display are purely coincidental. Every effort has been taken to prevent profanity from being generated.

PLATFORMER MINIGAME

Reach the exit door by jumping over the spikes. Click the jump button on screen to start the game and press it again to jump over spikes.

CAFETERIA MINIGAME

Serve up the correct orders for each employee before time runs out. When you're ready, ring the bell to start the clock and check the order at the bottom of the screen. Use the recipe book (blue book icon) to determine what to make and click the required ingredients for the requested quantity. Ring the bell when you're ready to serve. As the difficulty increases, more orders will need to be served to continue.

Note: different players can read the recipe book while others cook at the same time.
