Termalloc is a top-down 3D shooting game. You can move forward/backward and left/right, but you can not jump.

There are 22 pentagon-pillar-like terminals in the field, and your mission is connect all of them to the server.
While connecting, terminals turn yellow, and green if connection is complete.

Guards are coming to stop you. Shoot them to keep yourself safe.
Guards get faster every time, and more and more are coming.
Guards sometimes drop a coin which you can pick up and buy upgrades.
