I haven't played this, but that's being remedied currently. Also, holy shit spoilerz ahead (if that wasn't obvious already).
A childhood friend has recently come to live with us, and he owns the original Half-Life (and an expansion or two). So I've been playing this week, and now I'm in the process of beating Surface Tension. I've sunk a good amount of time into it so far and enjoyed myself for the vast majority of it. The game is dated yet extraordinarily compelling.
What I Liked:
- The music - For obvious reasons
- The lighting - I was expecting much worse for a game this old.
- Black Mesa Inbound (Chapter 1) - And I thought this long train ride would be boring.
- Anomalous Materials (Chapter 2) - Resonance Cascade, bitches!
- Unforeseen Consequences (Chapter 3) - Running through a devastated area after previously seeing it in pristine condition was really neat.
- "We've Got Hostiles" (Chapter 5) - Yankee doodle comes to town.
- Blast Pit (Chapter 6) - Realizing that the Tentacles are totally blind and only hunt through hearing was an awesome lightbulb moment.
- On A Rail (Chapter 8) - Rail shenanigans, death threats scribbled on the walls, and finally launching a rocket into the nighttime sky.
- Apprehension (Chapter 9) - First being surprised by and then finally taking down the Icthyosaurs was an epic triumph. At the end Freeman is captured and thrown into a massive garbage crusher- What can I say? Unexpected and full of oshi- moments.
- Residue Processing (Chapter 10) - A meat processing plant from hell. Riding the conveyor belts, avoiding the crushers and furnaces was great fun.
- Questionable Ethics (Chapter 11) - Giant lasers, a bunch of aliens attacking marines, and other chaotic goodness. This is also the level that marks the appearance of the Tau Cannon. Pew pew pew! I love that thing.
- Surface Tension (Chapter 12) - Jets, cliffside battles, blowing up a helicopter, blowing up tanks and other armored vehicles, etc.
- Assassins - Sooo satisfying popping around a corner and blowing one away with a double-barrel blast from my shotgun.
- HL1 Headcrab zombies - I spied them doing some really creepy things, like crouching over corpses or carrying dead bodies under their arms. Their super-long claws and resulting extended reach freaked me out at first.
- Forget About Freeman! - Short, sweet, and lots of explosions.
- Lambda Core - Lots of wheels and switches to activate on all kinds of scientific equipment, and then there's the climactic teleportation to the alien world.
- Gluon Gun - BZZZZZZZZZZT POOF!
- Xen Very short chapter, had some interesting jumping mechanics.
- Interloper I liked it, there was some unique puzzles and there were plenty of healing pods scattered around so it didnt get too tough.
What I Disliked:
- Excessive amount of hallways/corridors in some levels - Felt slightly repetitive after a while.
- Office Complex (Chapter 4) - The level managed to creep me out at first, which is a plus, but I didn't really find the level very interesting or compelling at all.
- The occasional grenade spam by enemy soldiers (Damn things are laser-guided)
- Lack of checkpoints - I'm getting used to doing it manually, but it's still a nuisance. Thank goodness that they fixed that problem in HL2.
- Xen? (I haven't reached that point yet, but I hear it sucks)
- Minor annoyance, but I noticed that there are some walls you "stick" to for brief periods of time, can be very distracting in combat.
- Gonarchs Lair Giant ballsacks that soak up a ton of damage arent really too much fun to fight.
- Nihilanth - Would have actually been fun if the Nihilanth didn't spam teleporter blobs at you. I spent the entire game fighting to get at this giant spacebaby, don't take me away at the worst possible time! Overall, a pretty frustrating ending.
Many aspects have aged (Graphics, sound, AI [No way it's more advanced than the sequels]), but I can easily see it every one of those 50-ish game of the year awards.
In Closing:
If you haven't played this yet, bloody get around to it! If you can stomach the low poly environments/characters and low res textures you'll have a blast. It's considered one of the best games of 1998 and of all time for damn good reason.
