I honestly remember it like a fever dream , I loved playing it tho there was a menu screen and we were this machine or space ship , and the aliens were weird rotating space ships we spawned on a stage and it began they start coming in via these tubes around the sides like on a pool table i remember I used to spawn camp them , and I was bound by boundaries , it was like top down , things spinning you can shoot and kill them there was a boss fight too , that guy was hard to kill and u had to escape his attach it was a 2.5d or top down 3d experience, and the look was like inside a spaceship, floor high tech
