I am sorry that you had to experience that.
Now that you mention it, I think many are going to experience this. I should have not done this in ue5 or should have disabled nanite.
Thanks for trying game and posting comment.
Actually, you didn't missed much.
There is only one level, all art pieces used are pre existing (from sketchfab). There is an alien ship and it's huge(shown in one of screenshots), we play as a drone and we fire bullets only when batteries spawned randomly are somehow in physical contact with our drone. Alien ship fires at you and occasionally spawns a bot chasing you.
Our drone has magnetic properties, so it attracts batteries and metallic weapons. Batteries allow you to fire and weapons take your life away, slowly.
