Requiem of Hell is an action-RPG game exclusive to Nokia N-Gage, and the closest thing to Diablo you can get on this platform. It has isometric graphics, hack'n'slash action, hordes of deformed monsters, and of course, Hell.
The game starts in a village that has been attacked and ransacked by demonic troops, and your character is among the slaughtered ones. The magical fairy and a mysterious shaman brings them back from the dead to fight their cause.
Action is done a bit differently from the Blizzard hit, as you may not only attack, but make combos, also use special moves depending on a weapon in hand, block enemy hits, which might be essential, and cast several types of magical spells. The character only has a health bar and instead of stamina there are cool-down timers for magical attacks like in MMORPGs.
The roleplaying system is a simplified one as you level up mostly automatically, magical skills get more powerful the more they are used. The fairy accompanies the player during the journey, and can help him with an advice or slightly heal him if health gets very low. Hit points could also be restored with various food that lies around on the map.
There are also two multiplayer modes: one is for cooperative play, and another one that allows two characters to battle against each other.
