Prepare ammunition
The official description tells players to grab shells. Treat ammunition preparation as a team task: communicate when a cannon needs loading so the crew can keep its attention on the defense.
The public listing does not give shell types, capacity, reload times, or damage values. Those details should be checked in the current game rather than inferred.
Load a cannon
Loading a cannon is explicitly part of the advertised gameplay. Follow the current on-screen interaction prompts; exact controls can differ by device and may change during Alpha development.
Do not rely on control keys from unrelated Roblox shooters. The game page does not publish a control chart.
Coordinate firing
The premise is cooperative PvE defense. Before firing, call out which cannon is ready and what the crew is targeting. This is general coordination advice; the listing does not describe target lock, projectile physics, or a scoring bonus.
Use in-game feedback to learn how shots behave. Avoid assuming a fixed firing cadence until you have confirmed it in a live round.
