Battle mode
Successfully complete the game. The game will automatically
save after the credits have completed. A battle mode option will
be unlocked at the main menu.
Linear launcher
Get an A ranking with Steve Burnside, Chris and Albert
Wesker and both versions of Claire in battle mode to unlock the
linear launcher. It will appear in your inventory during the next
battle mode game.
guns
While playing in battle mode, kill all but one zombie
in any room. While equipped with sub machine guns, walk up to
the zombie and press [X], and Steve will cross his sub machine
guns. For best results, play in third person so you can see the
cross-fire. If there is more than one zombie, Steve might aim
at two zombies rather than cross-firing at one.
Play as Albert Wesker in battle mode
Take Albert Wesker's sunglasses from the floor in the
Incubation Lab after the intermission sequence when playing as
Chris. Alternately, perform well in battle mode with Steve Burnside.
First unlock Steve Burnside. Then, play as Chris and finish with
the best grade to unlock Albert Wesker. He is armed only with
a knife and has two mixed herbs.
