Battleswarm allows up to six players to take control of soldiers in team-based, first- or third-person shooter mode, arming themselves from a huge arsenal of high-tech weapons and armor. They compete in discrete missions versus up to four Alien Commanders, who control hundreds of bug-like units in real-time strategy mode. The Alien Commanders must build hives, breed units, and manage their forces in missions to overwhelm the human opponents. Players can create guilds, buy and sell items, and level up their characters.
