Here is a new version of the famous PC game, the Counter Strike in his version for PSP. You can play multiplayer via wifi between PSPs and move in the new maps among other things. This latest version allow you to play against enemies (bots) in "Single Player" or "Multiplayer" against other friends via Adhoc. Most players find this game more realistic compare to the original PC game (especially in the maps), if you played the original, this will surely surprise you how close this version to the PC version.
This game, like the original Counter Strike, is designed for online play. So if you do not have any buddy to play with dont worry because you can still enjoy this game in "Training mode" whether alone or with bots.
