Terracom have a problem.
Experimental war-droids built using ancient alien bio-technology have gotten out of hand, now Terracom's secret underground labs have been overrun by hostile machines.
There is a solution: Developed by a rival Terracom military-products department, the Terramek is a state-of-the-art turreted bipedal war machine with interchangable weapon systems.

Kill everything on all 8 levels.

Collect treasure dropped by dying enemies.
Destroy crates for more treasure and sometimes powerups:
Yellow - Nuke
Blue - Weapon Coolant
Purple - Shield
Red - Medic

Find exit doors located at the edges of the level map, (indicated by arrow tiles on the floor),
to leave the level and buy upgrades in the shop.

Avoid overheating guns (watch temperature bars in bottom left corner).

Move with WASD keys (or arrows).
Aim and fire with the mouse.
Cycle primary weapons using Q and E.
Cycle secondary weapons using Z and C
Activate shield using X.

From the map you can teleport into previously visited rooms.
