Basically to play, use your mouse to move your units, to attack the computer player. The game uses a Rock / Paper /Scissors type of game play for the combat, with each unit being superior to something, but inferior to another. The units available through Battalion Nemesis include Heavy Commandos and Strike Commandos. Strike Commandos are more effective against light armour units like Commandos and trucks.

In later levels you can take over buildings, to create extra units, and secret levels will also be revealed to you as you complete various tasks. It becomes more of a challenge as the computer player has more units, is more intelligent, and the maps are larger. Overall Battalion Nemesis is an enjoyable online war game. If you like turn based war games, you might also be interested in Battalion Ghosts which is episode 2 of the Battalion series, or Battalion Vengeance which is episode 3
