Aliens Nest Game

Aliens Nest drops you into a secret military base that has gone dark, and it isn't hard to see why: alien invaders have taken it over, and a handful of human collaborators are helping them from the inside. You're sent in alone to find out how deep the betrayal goes and shoot your way back out.

It plays as a straightforward corridor shooter. Rooms and hallways are tight, enemies come from doorways and vents, and you're expected to clear each area before pushing forward. A full arsenal of weapons is available as you progress, so part of the appeal is finding the gun that suits the next room rather than sticking with whatever you started with.

Controls

Move with WASD. Aim and fire with the mouse.

It's a quick pick-up-and-shoot session rather than a long campaign, which makes it a good fit for a short break between games.
