There is a couple of problems with the lambda core teleportation room that I have noticed.
The scientist that starts the machine going can be killed and this stops the sequence he is currently set to not be critical to mission to keep alive. Try it out if you like for a laugh but he needs to be made critical to the mission.
Acording to the commentry where it is said the devs planned to have an alien controller attack him this might be a nice update that you have to save him before loads start spawning in after he says we have a breach. This would be a nice introduction to the new enemy Then on death of the said controller this would spawn more controllers in to the area and make him even more mission critical
Although it sounds great in the teleportation chamber the sfx volume of the teleport sequence is just a bit too loud of the machine whilst not wanting to lose the imapct that it has it needs to be lowered just a bit…
Other than this the whole sequence is Briliiant but this is not really a bug fix more a tweak to the overall way it works.
