The needs of the many outweigh the needs of the few, but technically you're both parties in The Shpufa's gory puzzle platformer Infinity Inc. Turns out when you start cloning people, you can wind up with a lot of trouble on your hands, and this old facility has seen a lot of bloodshed. To escape, you'll need to make use of the cloning gun to make duplicates of yourself to help get past hazards, but hey... what could possibly go wrong this time? To play, use one of the two optional control schemes... I was partial to the [arrow] keys for movement, [X], [C], and [V] to erase, clone, and swap control respectively when available, and the [spacebar] to self destruct if you get stuck. The number of clones you can spawn once you find the cloning gun is in the upper left corner, and you can control them to do all sorts of things, like trigger traps so you can pass by safely. After all, they're just expendable clones, right? The gun can also be used to erase certain blocks out of existence, but you'll need to scour the facility for keycards and more if you want to get out alive. One of you, anyway.
