Incredible multiplayer - fast, refined, intuitive, easy to play and difficult to master. SP is the same as past games.
This game shines, however, in its THIRTY TWO MULTIPLAYER MODE.
It just feels good to say that about the Wii.
Sniping, protecting your flag, ownzoring the enemy, team tactics, they're all here. No vehicles, planes or truly giant spaces, unfortunately, but this game is a blast and there are plenty of servers with folks to play with.
My 10yo daughter managed to figure out a good spot to surprise people at and took out the one guy on the enemy side who kept stealing their flag. Then folks started following her around, and since she'd been on the enemy side before switching and knew their base, she made a flag run. She described her "parade of DOOM", 10 players, almost the whole team, ran with her, and they mowed over the resistance. She got the flag and brought it back.
After that, the enemy was in disarray so she sneaked in and got the flag again. Then she guarded her flag and killed people who tried to get it - PC owners note: folks on consoles are truly impatient, rarely do you see someone patiently guarding the flag room by themselves, so my 10yo's tactic worked great here.
Then folks got tired of losing and started leaving the server. Ownage. By a 10yo girl and her team-mates.
If this story sounds fun / funny / awesome, get this game.
