All Guns On Deck casts players as a young sea captain serving Eutopia, a nation rebuilding its navy for a campaign against foes with aerial superiority. The setting pairs a broad conflict across continents with a more immediate danger: the oceans are home to threats that once drove sailors away. That mix gives the strategy and action RPG premise a distinctive naval focus, rather than treating ships as mere transport between land battles.
Combat centers on a warship that can be armed with as many as five guns. Players may control weapons directly or manage the crew, whose roles include welders, engineers and firemen. The game also describes clashes between ships and airborne enemies, port captures, attacks on enemy garrisons and battles against colossal sea monsters. Finding items and consumables, choosing weapons, and sailing different vessel types, from cruisers to aircraft carriers, round out the campaign’s tactical choices.
The store lists All Guns On Deck as single-player, so its format is a solo command experience rather than a team-based online match. Its combination of direct gun control and crew management gives the naval battles their central strategic tension.
