Unlimited Zig Works writes: "The Revelations demo showed me an unimpressive but competent return to the older style of Evil, where ammo conservation actually matters, and some enemies must be spared to save those shotgun blasts for the end. It’s taxing, in a good way . . . on the “hell” difficulty. On the “normal” difficulty, the Revelations demo was a dull exercise in walking from one room into the next room, with occasional interruptions by shambling non-zombie lurkers."
