So there was indeed a cow.
Walls before attack (WBA): You must touch all the marked walls before you're allowed to attack your opponent.
Crate before attack (CBA): You must collect at least one weapon crate before you're allowed to attack your opponent.
Attack from rope or parachute (AFR) (AFC): You can only attack while hanging on a rope or while using your parachute, unless the weapon that you're using doesn't permit that.
If you break any of the rules mentioned above (WBA, CBA, AFR) you must not attack your opponent during your next turn, but you're still allowed to get your crate.
Permanent blocks are not allowed (e.g. with bow), blocking with worms is allowed. If you block your opponent permanently, the match will be voided or victory will be given to your opponent.
If you win the match by breaking a rule, the match will be voided or victory will be given to your opponent.
