Haha, I've been waiting forever for them to add Achivements to CS:S. I'll give it a go, but I can't just play that all summer
I finished up some FPSes recently, as well.
First I got ahold of the Chex Quest 3 WAD, which is all three episodes (minus the intro / extro videos on the original CD). The original was really square and rather bland, and the final map never has made sense to me (I've played through it before) as it's a pretty straight shot to the massively underpowered "boss" (something like a Mancubus frozen in place) and most of the level doesn't need to be visited. As a result most people might not even realize there's more to that one (due to the whole thing about not seeing the stats on the final level of a DOOM episode). It got better for the second episode, a little, and the third as well (though the final map of the third level is also aggravating; switches for color-coded doors).
The main thing holding all of the Chex Quest episodes together is Charles Jacobi's artwork; the actual gameplay is kind of lacking - hard to believe since it's DOOM. Who knows, maybe DOOM is boring too, now, but there is some extreme confusion about which Zorch goes where (ammo types) and while all the weapons are there, the game's difficulty mainly lies in there being not nearly enough ammo, and good weapons not showing up until later. Playing on the Ultraviolence analogue (i.e. second hardest next to the one with respawning enemies, which still starts off pretty easy), most of the difficulty came out of the good weapons not being available for very long. As a result I hit the IDFA cheat (and it seemed to change from the first episode to the second, strange) so I could get the shotgun from the start. Most of the enemies are melee zombies only, with no ranged attacks! All the enemies have some green in them (slimy) but the different looks makes it pretty easy to tell one from the other. Great music in a few maps too. Overall: It's free, and has a fun personality, but it's kind of skippable. Maybe if there were some tougher maps with more appropriate ammo / weapon placement I'd come back to it (on the other hand, it plays significantly different from DOOM on Nightmare due to enemies not having instant-hit weapons for the most part, so you can actually tackle this one if you just run away from everything). The museum and the movie theater (Odessa Steps scene!) have a lot of great art in them, in particular.
I also played Soldier of Fortune II again, Gold version, on Consultant (next-to-hardest difficulty). I set up the game for widescreen using the hex edit method from Widescreengamingforum and it made a big difference. The non-stretched stuff wasn't much of a problem. I started to get bored with the whole "switch between USAS-12, M4, OICW, and MM-1" deal about halfway through the game, but I stuck with it this time - I think I must have cheated before because some stuff was new to me. Too many hallways at the end of the game. The art and areas start out strong - I think my favorite parts are actually in the beginning "prequel" mission, set in Prague. There's more good stuff later but eventually it becomes just a bunch of conventional stuff, and the last office is an office building - lame.
But I appreciate the game more now that I realized that M4 grenades are plentiful, the USAS works wonders, and the MM-1 machine projector is also indispensable. Also beat the final boss the right way this time without too much fuss - a lot better fight than SoF1's endboss.
I used tons of saves, though, and also had carrying capacity turned to unlimited. It's definitely a difficult game. I did pretty well most of the time, though.
What dragged me down were mainly invisible barriers (quite a few) and especially grenades (launched and thrown) loving to catch a corner well to the side. The launched grenades (with the exception maybe of the MM-1) won't even arm at the sort of distances, though it does make it more convenient to suicide and try again...
