It's been a very long time since I posted anything related to Doom here.  Last Saturday afternoon, I downloaded a couple of WADs and was playing them, so thought I'd write about them.  Here are the two mini-reviews —

Dead Perfect by Yonatan Donner

Two small Hell Revealed-style maps from 1997, replacing MAP01 and MAP02 of Doom II.  The text file says that these maps were initially made for Pursuit, and were originally deathmatch maps, later converted into single-player.  Therefore, both maps feature interconnected rooms and some symmetrical designs.  They're both packed with monsters and weapons.  I played both levels on Skill 1 only, and had quite a good time.  The maps are both quite good-looking and use only stock Doom II textures.  The author used some interesting features like having monsters stay in their place until being activated at a later point of time.  Should be an interesting set to blast through sometime — better players can try the higher skill levels.  Yonatan has provided demo recordings for both levels in the set.  For some reason, I got the nagging feeling that I played both these maps before.  Anyway, good stuff.  7/10.

PN Slime Base by PirateNipple

As far as I can tell, this is the author's first released map, and it's a well-made one!  It starts you off in a green-brick courtyard and then takes you through some varying environments, sticking to the "slime base" theme.  No new textures used here, only the standard Doom II ones — towards the end the author throws in some more demonic marble-type areas slightly reminiscent of Ultimate Doom Episode 4.  It's quite a straightforward map route-wise, and there are some nicely staged fights.  An underground dark area especially provides a good surge of adrenaline.  You'll have to be careful with your ammo here and use the chainsaw provided as much as possible.  I wasn't careful, so I ran out of ammo in the very last area and completed it by cheating.  Otherwise I thought it was quite nicely balanced, and not too tough even on Skill 4.  8/10.
