Medal of Honor Heroes Q&A - The Greatest Little War

Heres an excerpt of the Q&A session at Gamespot

GS: Have you tailored the gameplay in the various campaigns to be more PSP friendly--playable for short stretches at a time?

Given the portability of the PSP, Heroes will offer objectives that can be completed in short amounts of time.
PC: We have definitely tailored the game for the PSP with the on-the-go nature in mind. Missions have several levels of objectives and stats that can be achieved, allowing for different levels of depth and time investment. Plus, each mission can be replayed to earn higher ranks and medals. We've also added a brand new single-player skirmish game mode, where players can play a quick, one-off mission scenario and can customize the scenarios for endless replayability.

GS: How did you approach the multiplayer modes in the game? Will they offer both ad hoc and infrastructure connectivity?

PC: Multiplayer is one of the most exciting features of Heroes. We have 32-player infrastructure support with continuous joining so players can simply pick a server and jump in anytime. There are 15 different maps and six different multiplayer game modes, which are mostly team based. We also have a new innovation on the PSP that allows players to download a user-hosted server to their own PCs and run their own dedicated servers. Both user-hosted servers and EA Nation server games are fully customizable, and we have very detailed leaderboards and stat-tracking. Players can also play all these multiplayer game modes and maps with up to eight of their friends in a local ad hoc multiplayer game.

Great news. I hope single player doesn't involve too much squad-based nonsense.
