It is possible to dive through the long tunnel in Lambda Core leading into the reactor room without taking any drowni...

It always bothered me that you had to take damage in that tunnel, so it makes me even happier to learn that it doesn’t have to be this way! Hooray.

I could be wrong, but I am pretty sure that was a swan dive.

lol, yeah I had to do that a few times… nothing like going through there with 23 HP and surviving till the next medkit.

Mr. JP could have intended to make it longer than it’s respective HL counterpart since the original one bugs players so much when they try to reach the end of the tunnel. The original one was shorter to the one in BM yet what was different is that, here the player is much faster than in HL.

Trust me, first time I tried playing this area in HL (with cheats of course, since I wasn’t really able to finish HL without cheats because I was scared of the Alien Grunts) and I never reached the end of the tunnel.
