[TAS] Half-Life - Apprehension train v2

A remake of an old TAS of mine • [TAS] Apprehension tra...
This time on default Steam version, new FPS tricks and improved reference.
Exploring the opportunity of combining unlimited velocity under water and 0ms frame object boosting. With 0ms you actually have frames enough to reach the insane speeds without interruptions. I noticed speeds well over 100k ups. And since there seems to be no velocity limitation/axis under water, any desired horizontal angle can be used without being forced into diagonal velocity that typically happens in non-water environment.
Using a 4 fps trick on the rotating doors. The door starts to open at the start of the frame even though you don't reach and touch the door until the end of the frame. Saving nearly the full frametime of 249ms compared to 1000 fps.
FPS values used:
4 - door openings
20 - water entry
100 - edgebug
1000 - strafing
10000000000 - ducktaps and object boosting

0:28 Slowmo splitscreen
Timings:
12,260 under water 41|0
12,424 tram route 85|15
13,9 old water route TAS
The result speaks for itself; only 0,164s faster with a great loss of health.
Worth noting is that going in the water all the way until the grenade boost is about 0,2s slower than going up the stair. But this was the way I found to work without any armor for minimun damage.
Trivia:
The train HUD shows only three of the actual four gears.

Physicist goes faster than the speed of light in water. Technically he should emit Cherenkov radiation.

We boosted the anti-mass spectrometer 105%. Bit of a gamble, but we need the extra resolution.

[@TheArzonite]

Man, this is some great stuff. Is there a full HL1 TAS anywhere, or is there someone who's working on a full run?

[@quadrazid]

Thanks! Unfortunately there is no full game TAS. But I'm hoping to inspire with these clips and also make good references for a full game TAS plan (hopefully) eventually.

[@rickhapstley3866]

So glad you're back ! Do you think a sub 20 run is possible ?

[@quadrazid]

A TAS of HL is more like 18-19 minutes I'm guessing :)
