Infernal: Hell's Vengeance is a forgettable shooter that spends more time irritating players with imprecise controls and illogical puzzles than it does thrilling them with tight action or killer set piece battles. The save system is another annoyance. There is no autosave option or checkpoints, so you must remember to save manually. Although this make it easier to bypass the trickier portions, fiddling around in the menus takes too long, destroying much of the appeal of quick saving.
Even the best moments of Infernal, when enemies are swarming and explosions are going off all around you, are hampered by a stuttering frame rate that make these sections nearly unplayable. It doesn't matter if it's bargain price, full price, or flat-out free, Infernal is not worth your time.
