1. The Shuriken The damage per hit is extremely high,and it has a respectable reload time.

2.The Gun Good Fire Rate, Good Damage and an even better Power-Up

3. The Crossbow High damage and very good Power-Ups. I got the Pre-Selected 10 wins v Cpu WR with this

4. The Sniper Shoots the most powerful projectile in the game, buts ranks as no.4 as its reload speed is low

5. The Laser Sword Multiple Power-Ups, each one powerful in its own right, make the Laser Sword the 5th best weapon
