Game concept:

The last Human Shelter is under siege by self-replicating alien robots! It’s up to you to to salvage their parts and save humanity! Build a mech to defend against waves of alien robot hordes, reprogram their tiny minions to serve you as pieces of your mech, and strengthen your defenses to fight back the horde in hopes of a new dawn for humanity.
