Crash Bash - Level 15

Crash Bash is a party game for up to four players, with computer AI making up the rest. The game features several mini games requiring different objectives and tactics, although the general goal is to defeat all the other opponents by reducing their health to zero or otherwise knocking them out. The last man standing wins the round, with the winner being the first to win a set number of rounds.
The main mode of play in Crash Bash is the Adventure Mode, in which one or two players must win all 28 levels to complete. The player(s) wins Trophies, Crystals, and Gems by beating the different challenges of each level. Certain levels require a minimum number of Trophies, Gems, or Crystals to gain entry. There are five Warp Rooms and completing all of them results in a 200% completion, although this doesn't unlock anything.
