CastleStorm

The multiplayer is easily boosted either with a friend or a second 360. Here's how to get all the ranked match achievements in about 10 minutes:

- Both players should equip the best castle and their favored projectiles and troops. Vikings should have the boar rider and Kingdom should have the knight on a horse, and both should have both their hero spells.
- Have player 1 win three times by sending their troops to grab the flag, while helping to take down the door with projectiles and maybe a hero or two. Player 2 does nothing.
- After three wins, player 1 should be level 2.
- Have player 2 win once and you'll have all achievements and be done if you're dualboxing. If you're boosting with a friend, have player 2 level up to level 3 (unsure how long this takes since I dualboxed, but probably less than 10 wins).
- Have player 1 win once more, for this final achievement.

If you're having trouble connecting, it's probably because you're used to searching at the same time in most games. In this one, however, one player needs to search and establish a room first, then the second player can search and find that room. It doesn't create a room as you search like most games do.
