Unfortunately, if you are looking for massive instances with multiple players, you’ll have to look somewhere else. PvP is one-vs-one or two-vs-two only, and that is the only option. Thankfully, the PvP arenas are of a small enough size, that this isn’t too much of a problem. The arenas themselves have environmental hazards, such as fire shooting up from the floor.

Ultimately, it looks like PvP will be a fun little addition to Darkspore. I think there needs to be a bit more to it to make it the hardcore multiplayer mode people might better like, but it’s an addition that suits the nature of the game. I suspect the campaign, which can support up to four players in AI directed levels, will be where most players spend their time, but using their best fighters in a battle is something many gamers wouldn’t pass down.
