With up to four-person online or local multiplayer available in vs. or team battles, Military Madness experts can compete with each other across the world. Multiplayer maps are also specifically designed to be balanced for 2, 3 or 4 players. The addition of the multiplayer-specific Commander unit allows players to customize their strategies before a battle by spending points to select abilities that improve the Commander unit itself, improve friendly units or disrupt enemy units.
The game features two opposing forces with near-future military equipment battling it out on the Moon. Each level is a distinct map with a hex grid, on which players take turns moving their units in an effort to win by destroying all enemy units or taking over the enemy headquarters. Like the original game, Military Madness: Nectaris players strategize by the placement and movement of units, make use of terrain advantages and predict enemy movements to outsmart the enemy.
