There's a large amount of enemies to see and interesting things like exploding walls, stages with ankle deep water and skeletons that come out of the walls. It's primitive, but a lot of fun. Especially the first episode (each episode has it's own sub title, so Catacomb Abyss is the first episode. Catacomb 3D is the collective name for them, but they exist as separate .exe files only, as far as I know, rather than a Wolf3D style episode select menu).

Blood is widely celebrated as a great Build engine game. I got tired of it and think it's a bit unbalanced and annoyinng, but as long as it's still new to you, you would probably have a blast exploring it. It's got a pretty cool horror themed thing going and is quite creepy and atmospheric. Episode one was the best. After that it gets a bit annoying. I recommend not playing at too high a difficulty level, but I do recommend checking it out if you like Duke3D and Shadow Warrior.

Eradicator is pretty obscure and feels a lot like a build engine game. It's got some odd sci-fi themed graphics and will not seem very appealing at first. But the well kept secret of this game is that it's pretty solid and has some inventive features and a large selection of weapons. Also has some pretty big stages and a cool, ambient soundtrack. And 3 characters to play as, even! I like it quite a bit, but it's an odd game, admittedly.
