Ace Combat 6's co-op battles support up to four players simultaneously, and task gamers with destroying overwhelming enemy forces within a time limit. Each pilot can choose to fly in a different plane, so it's entirely possible that well-organized teams will choose to use specific planes for certain roles in the battle. All of the planes in Ace Combat 6 have different handling characteristics, of course, but their most distinguishing features are the various special weapons in their arsenals. The F-16 that Gamespot opted for, for example, had a special weapon that could lock on to four enemy aircraft and fire rockets at all of them simultaneously. Gamespot also noticed that there were three other special weapon options for the F-16, but they need to be unlocked--presumably in the single-player campaign--before gamers can select them.
