Alien Terminator

You control a small, armed character, often a soldier, moving them across the screen with your mouse. The moment to moment play is about constant motion and clicking. You run, you shoot at the swarming creatures, and you try to avoid getting surrounded. Your main objective is to clear each wave of aliens. Recognizable mechanics include picking up weapon power-ups that appear, which change your firepower temporarily, and watching for health items to survive longer. The pacing is relentless; the difficulty comes from the increasing numbers and speed of the bugs. It feels like a tense, repetitive scramble to stay alive just a little longer.
