Effect: Hold Extra Grenades
When:
In game
How:
Normally, you're only supposed to hold 6 grenades but when you have a grenade thrown at you you can pick it up and throw it again. Instead of throwing it you can keep it for later by pressing the minus button a second time after picking up a grenade. There's no limitation of grenades when doing this
