"If you're a fan of Tormentor667's work, Austerity will not disappoint. If you aren't familiar, let me elaborate."
What's here are three maps of a good length. Long enough to not feel cheap, but not so long that it drags on. There's some good surprises to keep you guessing at how far you are into the map as well, with plenty of ambushes to keep you on your toes. When I use the term "plenty of ambushes" I mean to say that every time you open a door, grab an important item, or revisit an area you've been through, you're going to get swamped with powerful enemies. Most times this was well done, and it's nice to go backtracking and have something to shoot at while you're at it. Later on, though, it becomes almost frustrating and predictable, especially considering the volume and power of the enemies that come out all around you.
Playing on Hurt Me Plenty is hard enough. I'd suggest anyone who doesn't want multiple deaths and retries to play on I'm Too Young To Die; there's really that many enemies. I struggled to make it on Hurt Me Plenty, eventually resorting to cheats in the third level, as my screenshots show. That said, there's a good balance of ammo. Enough that I had to conserve shotgun shells and use the chaingun or other weapons. I'd say if you can handle that many enemies on you at once, you'll find the ammo will fit perfectly.
The aesthetics of the map are incredible, which is expected of Tormentor's work. The screenshots highlight only some of the great set pieces that are used and detail is consistent throughout all the maps. There's some real eye-candy to be found. If you're looking for a good example of how adding a border or a window or a little bit of curve can really enhance a map, this is a good place to look. It's clever, it's high-quality, and it's hardcore enough that anyone should be able to get enjoyment out of it.
