Gameplay:
With Killzone 2, Guerrilla Games aims to provide the player with an immersive and cinematic gameplay experience that is grounded in reality with what they call "Hollywood Realism". The game is almost entirely presented from a first person point of view, through Sev's eyes. Killzone 2 features a cover system named "lean and peek" which allows the player to take cover behind an object, and then pop out to fire at enemies. The "lean and peek" mechanic stays in first person view at all times. Killzone 2 will also support PS3 Trophies. It has also been announced that Sev is able to pilot vehicles, however further details are yet to be announced. Many Killzone classic weapons and vehicles such as the the M82-G and the StA-52 LA will be returning
AI-Bots:
Killzone 2 has been confirmed to be supporting AI bots in multiplayer, both single player and online
Multiplayer:
Killzone 2's multiplayer component has been developed by Guerilla Games in parallel with the game's single-player campaign.The multiplayer gameplay is class-based, meaning the player can choose a class of character which is specialized for a specific role to better suit the player's needs in battle. There will be 16 abilities(badges) in total in which the player can mix and match 2 of them according to their playing style, and can switch abilities upon death. 32 players can connect online, and group into squads of up to four players. Two squads can group together as a faction of eight players. Killzone 2 also offers a clan system, which allows clans of up to 64 players to compete for "Valor Points", an in-game currency that clans can use to bet on tournaments.
In the level Corinth River, Sev is partnered with Garza, a fellow member in Sev's special forces squad. Garza is AI controlled, which has led to speculation towards the possibility of co-operative gameplay, where Garza's AI could be replaced by a human player. Although this is merely speculation, and more details on Killzone 2's Multiplayer have yet to be announced.
