Weapons MasterG 15

This achievement has a misleading description and is slightly glitchy. Doing all of the things on this list seems to be a fool proof way to unlock it.

List of required attacks:
- Hit an enemy with the Disk.
- Kill enemy with a Disk explosion. This works on a timer, it will explode a couple of seconds after it has landed
- Hit an enemy with the Paper Airplane.
- Kill an enemy with a Paper Airplane explosion. Press B again to detonate it.
- Kill an enemy with the Wall Hugger (Bomb frog).
- Kill an enemy with the Acid Bubble.
- Kill an enemy with the Fireball.
- Kill an enemy with the Grenade.
- Hit an enemy with the Iceball.
- Hit an enemy with the Dodgeball.
- Hit an enemy with the Dart.
- Hit an enemy with the Boomerang.
- Use the Forceball
- Use the Fan
- Use the Vacuum.
- Kill an enemy with the Head Bounce. This is not weapon related. This is only possible to do in the Arena VS mode 'Soul Snatch.' Jumping on the head of an enemy in this mode is lethal to them.
- Get killed by a Head Bounce. Have an enemy jump on your head in 'Soul Snatcher'.
- Get a Head Bounce Stun. Jump on an enemy's head in the arena VS mode 'Grab the Gold'.
- Get stunned by a Head Bounce Stun. Let and enemy jump on your head in the arena VS mode 'Grab the Gold'.

Update: It seems you may need to be killed/hit by certain weapons as well for the achievement. If you have done all of the above steps check and see on the stats page. I have unlocked the achievement on multiple alt accounts playing in the arena only so this should be the only other stats you need.

If you are unsure which attacks you are missing, pause the game, scroll over and select Player Stats, and then press A again.
