Game description: In the sequel to the naval action sim "Naval Ops:Warship Gunner", video gamers engage in deadly sub-to-sub stealth warfare, pilot classic warships and design their own fleet of destroyers, submarines, and battlecruisers. With KOEI's strategic twist on naval action, Warship Gunner 2 lets players invest in new technologies to develop a full spectrum of artillery systems, aircraft, ship hulls, propulsion and electronics. Over 1000 vital components in all. Combat in Warship Gunner 2 takes place across 100 missions and 60 stages teeming with lethal seafighters, swarms of enemy aircraft, and unworldly super-weapons. Using the game's control panel and advanced heads-up display, players must track their targets through darkness, varying sea states and the most adverse weather conditions known to man.
The game is set in 1939 of an alternate universe, and thus combines technology of this period in the real world with a variety of futuristic lasers and weapons, without the "World War II-only" mode of the first game. However, the first playthrough is generally consistent with the historical World War II, while subsequent playthroughs feature more lasers and high-tech weapons, as well as a slightly extended ending.

Known Issues

Blurry 3D Objects

  • Status: Active
  • Type: Minor
  • Description: Occasionally during gameplay 3D objects will appear to double causing the objects to become very fuzzy and blurry. This will happen randomly off and on.
  • Workaround: Use Hardware Hacks/Fixes and set Skip Draw to 1,1
  • Comments: This seems to occur regardless of being rendered via software or hardware methods.

Fixed Issues

Effects visible through objects

  • Status: Fixed
  • Type: Minor
  • Description: When using hardware mode, various effects are visible through objects such as terrain, ships and buildings.
These include:
  • Distance fog (appears as a purple band along the horizon)
  • Bullet tracers, rocket/missile smoke and most energy weapon trails
  • Explosions and fires
  • Flares
  • Some animated models (e.g. lighthouses and the Floating Dock cranes)
  • Workaround: Use Disable Depth Emulation or Use Software Mode.
  • Comments: Fixed in 1.6.0.


  • Status: Fixed
  • Type: Minor
  • Description: When using hardware mode, shadows do not align correctly to their respective objects casting black but partially transparent shapes.
  • Workaround: Set Blending Accuracy to none/minimum (removes shadows entirely).
  • Comments: Fixed in 1.6.0.
