After watching the Killzone 2 multiplayer trailer, we wondered how much more fun the game's online mode would be without your typical multiplayer douche. Well, now we can find out! The upcoming FPS will, indeed, feature bots. These will be fully customizable difficulty-wise, and can fill in for players either online or offline, allowing any Billy-No-Mates to enjoy a friendly match every once in a while.

Additionally, vehicles are currently only available in the single player mode. Multiplayer vehicles will be patched in after the game is released. Also being patched post-launch is a co-op mode for the story. Whether this will be online or not, we're not entirely certain. Considering the long delay Killzone has suffered enjoyed, we're surprised this won't be included from the get-go. Perhaps we'll have to pay for it, but we're used to that by now, right? Be sure to check out our full Killzone 2 hands-on impressions, coming soon.

Update: Guerrilla has a history of making free DLC with Killzone: Liberation (PSP). It released an Infrastructure multiplayer mode and an extra single-player level months after the game's release.
