Ragnarok Tactics is a tactical role-playing game for the PlayStation Portable. It is a spin-off to Ragnarok Online.

Many centuries after the legendary Holy War that forced humanity to erect a magical barrier to keep both gods and demons from overrunning their world, the Branshaldo Empire and the Aura Republic engaged in an extended war for control of the Grantria Peninsula. The conflict eventually ground to a halt and an uneasy truce was reached, as neither nation had the resources to continue fighting. Even so, the animosity between the two parties never faded, but smoldered beneath the surface, always threatening to explode into flames. In the resulting tenuous peace, the people of the peninsula began to resume their normal lives, always aware that the war could resume at any time.

It was against this backdrop that the protagonist begins their fight against rival factions, hordes of ravening monsters controlled by enigmatic puppet masters, and even their own dark impulses...
