scavenge your ships for items, gear up, and battle the other ship.

Cannans can fire:
-Cannonballs (break blocks but do not explode or ignite TNT)
-Bombs (do damage, explode and ignite TNT, but don't break blocks)
-Mob spawn eggs (be warned, this shoots the mob itself, not the egg, so arch your shots high)
-Fire charges (set the enemy player ship on fire and will eventually ignite the black powder storage)

You'll find everything else you need on your respective ship, or plunder the other teams.

Remember to bring nothing into the arena, and sleep in a bed before you do (if you don't want to end up at home instead of play a second round.

If you're having trouble opening boxes, sleeping in beds, etc, try clicking with an item (not placeable like weapon etc.) or empty hand.

To "end the game" the last player alive has to kill themself, its the only realistic way for now, I will add another mechanic later.
