Spaceships litter the skies. Alien forces have come to eradicate human life. Who will stand against them? Who will answer the call to action? ULTRA FORCE has been called in. And even if the chances of victory are slim, they aren't going down without a fight. This is endless, point-hoarding, vertical shooter created for the OperaGX Jam 2021, where the game had to be kept beneath 5 megabytes and have multiplayer & highscore functionality.

The constraints made us think in interesting ways and act more cautiously. I think all of us are super happy with the end product!

good game... now give me freeplay mode




This was really fun. I would have like to have been able to have mapped fire to the mouse button to ease a little wrist strain, but that's on me.


Do you have a PB? If so, what is it, so I can try to beat it.
