Do you know who Nikola Tesla is? He's a famous physicist. Thomas Edison was his great rival and there was a combat going on between both scientists: the 'War of the Currents', between Tesla's alternating current (AC) system and Edison's direct current (DC) system. This game takes place in this context. Tesla's walking in a labyrinth where Edison's turrets have been mounted. Tesla must try to get through alive and to shoot down as many turrets as possible. You guide him in the right direction by pointing the arrows the right direction! After each level you can upgrade Tesla's team.
You mainly play this game with the mouse. Space bar = tactical mode.
