This single-screen shooter involves a grizzled grunt, his trusty gun turret, a garishly coloured boombox, and a seemingly endless supply of cigars. Our hero is partial to a smoke, see, sparking up a fresh one while you manage the inventory and casually flicking it to the ground when it’s time to get back to the grind.
Rock Gunar, to use his name, also seems to enjoy the task at hand – wiping out wave after wave of rampaging aliens, as they crawl along floors and walls in an attempt to reach the end of the corridor.
The only thing standing in their way is Gunar’s stationary turret. Kills earn credits, used to buy permanent upgrades, special ammo, various explosives, and stronger melee weapons. Only standard ammo is in infinite supply, so it’s wise to use special ammo sparingly. There’s no harm in being thrifty – it’s sometimes sensible to make do with standard ammo and slog through a few waves, saving cash for an upgrade that’ll make things easier in the long run.
Occasionally you’re forced to grind until you can finally afford the firepower to repel fiercer waves. It isn’t an unpleasant grind, however. At least, it isn’t for the most part – this is a game eager to please, throwing lifelines in the form of temporary perks, and giving the choice of a bonus power-up (air strikes, drones, double damage, etc) every time the combo meter is maxed.
As the game progresses – taking Gunar to new locations across a doomed space cruiser – certain upgrades become essential; a fact associated with the occasional difficulty spike. Only the riot shield can block sprays of acid, for instance, with acid spewers appearing around the halfway mark. If a certain wave is giving grief, it’s entirely possible to spend your gains on explosives and reduce all in your path to a burning mess.
