new blast pit route with hl21 obbo script

Steps:
1. Lower your armor to 19-22 by throwing a nade on the elevator. There are many possible setups, I usually do the one shown in the video.
2. Blow up the bullsquid, so its corpse doesn't block the box later.
3. The jumpbug from the box isn't necessary, but it saves some hp. For this jb you have to jump off the box in a crouch.
4. Make a nadeboost to the ladder. You can also use a script like this:
alias bp_nade2 "cl_pitchdown 30;cl_pitchup -30;+duck;+jump;wait;-attack;w 15;-jump;-duck;cl_pitchup 89;cl_pitchdown 89;force_centerview"
5. If there are houndeyes (or their corpses) in the way, you may need to throw a nade.
6. Perform this strat    • hl21-like blast pit obbo script  
7. Blow up the explosive crates with a shotgun to pick up the medkits later.
8. Pick up the medkits. at this point you need to have something like 60 hp at least.
9. Start charging the nade before changelevel, then switch to the shotgun and break the bottom plank, then immediately switch back to nade and release crouch, jump and crouch again as soon as it throws. You have to make the nade bounce off the floor. It's better to aim more to the right so you get less height and more speed.
2 mins of attempts:    • tentacle nade  


nade boost to the ladder saves ~5.7s
script loses about 3.5s (depends on execution)
nade boost in tentacle room saves 2.5s
