Wet is all about getting bloody. To perform well in the game, you have to minimize the amount of time you spend running around (minimize the distance), minimize the time it takes to kill each enemy, collect as many style points as possible so you can acquire unlockables more quickly, use power-ups efficiently, and successfully complete random Quick Time Events (QTEs).
The Crossbows are acquired just before The Opera House. These slow firing weapons use rounds that create a small explosion upon impact. It has the highest damage in the game, and is great at taking down groups of enemies.
