Helldivers supports four player co-op. It also supports cross save and cross play between the PS4, PS3, and PS Vita versions. Two players can play on a PS4 with two others joining in on Vitas in the same room.
As part of the elite unit called the Helldivers, you choose your deployment zone and dive into battle on procedurally-generated battlefields. Once there, utilize overpowered weapons and Stratagems to defeat the enemies of mankind. Working together as a team will be vital, whether calling in strikes or placing weapons, each action must be totally synchronized to achieve objectives. As with all Arrowhead games, friendly fire is a key part of the game, and if youÃ¢ï¿½ï¿½re not careful with the Helldivers explosive firepower, youÃ¢ï¿½ï¿½ll lose the mission and a few friends along the way.
