I played the game through a second time to find bugs. I wanted to share my results though I am certain some of the bugs have been reported already.
On the whole, I must say that you should consider taking a second look at Surface Tension again. The chapter misses some memorable moments from original game and has probably more bugs than the other chapters. I know a developer quit but you cannot tell me that it is such a difficult task to find another developer for this map.
Anyways, I want to present my results in detail. I have divided my list into 4 sections. Major issues should have top priority, of course. (Map-)Glitches are annoying little bugs that don’t break the game or make it a worse experience (with few exceptions). Suggestions is something you might take a look at but would only be a bonus.
MAJOR ISSUES
-
A.I. often ignores you although you are either in their view range or shooting at them.
Example: That alien grunt in Lambda Complex in the screenshot just ignores you if you keep standing there, even if you shoot him.
map bm_c3a2c; setpos -1407.760742 1014.547180 8.031250;setang -7.556681 71.784477 0.000000
Screenshot: https://www.abload.de/image.php?img=bm_c3a2c0002jwc5k.jpg -
Particle effects cause severe fps drops
-
Bad performance or engine crashes sometimes occur after reloading or after switching to windows and back to game again. In rare cases the engine is not even able to reload all textures again.
-
Balancing. Hard difficulty is barely more demanding then medium difficulty etc., see thread.
GLITCHES
-
Autoaim option is always checked in the Black Mesa Option menu after every restart of the game
-
No anti-aliasing applied to the crossbow scope view on AMD graphics cards (not sure about Nvidia with or without custum aa bits), not even SSAA which normally should work
-
If turrets have been activated and you quickload to a position nearby before the turrets have been activated, they are active anyway.
Example: On A Rail, see MAP GLITCHES -
Sometimes the ammo counter is red when the weapon is fully charged. Switching the weapons forth and back changes it again to yellow.

Sometimes the process of soldiers rappeling down the Osprey does not work perfectly and soldiers get stuck inside it, hanging in the air.
MAP GLITCHES
-
Unforseen Consequences: Flashlight makes the sign barely visible. This happens quite often in other maps.

Unforseen Consequences: You can climb up again from the water if you run up the broken bridge.

We’ve Got Hostiles: Two soldiers rappel down the shaft, but if you quickload, only one soldier is visible, and the other one is somewhere in the wall.

Blast Pit: If you quicksave right before the guard that gets into the rocket room draws the Tentacle’s attention to him, the guard cannot be killed by the Tentacle after a quickload to that postion.
This makes it much harder because the tentacles are not distracted by grenades anymore when that happens.

Power Up!: I know you cannot use sexy water here, but this is a very strange environment map. I think this is a glitch and not intended.

On A Rail: Sometimes, the platform just wouldn’t go upwards after parking the train on it. (If you kill the turrets upstairs before) And why can’t you drive backwards from here on till you get the next train car?

Questionable Ethics: Why can you actually break the servers here? You cannot do that anywhere else as far as I remember. And the server working sounds remain after they have been crushed disappeared.

Lambda Complex: Maybe that is intended, but it is barely possible to grab the hat on the lower rotating platform. You have to shoot it and sometimes it simply falls through the platform. And occasionally, you simply die on those platforms, for no apparent reason.

SUGGESTIONS
-
Reload sequence for magnum: Let Gordon reload just the amount that is needed in the animation sequence.
-
Apprehension: There are several places where broken electrified wires cannot harm you in any way, but here you get killed instantly. Maybe you should give a stronger visual hint here.

Jumping off a ladder and pressing the movement key (like e.g. runnig forward) simultaneously often does not work, this is not intuitive
-
Ensure momentum conservation for the player while jumping on some moving platforms or trains (e.g. the Inbound train), probably just an engine limitation but maybe you can fix that.
I’m looking into submitting these to the Bug Tracker.
