Got a weird glitch. On the first level of the human campaign, go to the first launch pad and jump while facing right. If done correctly, you should go straight through the iron beam, and straight through the bottom of the level, dying instantly.
@totolabion It depends on your play style.
If you prefer quick, low damage attacks, then I suggest falchion. If you are a tank, and love doing heavy damage, the axe. The sword is somewhere in between. Each weapon has different abilities, too.
