Single player games, especially low graphic ones, will sometimes do a bad job of portioning out what they have to offer. You'll either get everything at the beginning or have to go through bad dry spells where the enemies are the same, there's no new move to implement and you're using one strategy to clear everything. Or sometimes it's so easy to memorize when the game is going to give you something that it takes the excitement away. Project Warlock has so much great flow and progression that it feels like it was written like an album. Every new thing, whether it's a spell or a gun or an enemy, gets happened upon right when you're out of breath and wondering what the level is going to do to you next. It's exactly the amount of "oh sweet" and "what the hell" you want to hear yourself saying while playing a video game. And as a shooter, it gets to the guts. You are being ambushed and chopped at with axes while skeleton wizards shoot lightning at you as you realize two zombies are crawling out of the ground right where you are. Environments change, freaky new enemies get introduced, and you get weapon upgrades that are, in point of fact, actually cool. You will have a ball.
