Possible Achievement Bug(s)

I do so love the feeling of gratification from accomplishing arbitrary goals that no-one else will know about but me, so I really appreciate the achievements, but I think I may have stumbled across some bugs (or I’m just dumb–50/50 chance).

From the text, I assume the Caffeinated achievement meant you had to use 20 different vending machines, but I was able to get multiple points towards the goal per machine and accomplish it with just three machines.

Also, in Questionable Ethics, I think I did all 5 experiments, but only 3 registered.

  1. I killed the first alien grunt in the tube WITH SCIENCE
  2. I zapped the bull-squids and the headcrabs with the… ray emitter thing
  3. I gassed the headcrabs in the bio-chamber

I also zapped some grunts (both human and alien) with the second ray emitter in the cryo-chamber, which didn’t count. I feel like a pushed another button, but honestly, I can’t recall.

So, am I missing the 4th and 5th experiment, or did it not register?

You are missing something. The experiments register correctly.

I have the same problem of the 4th and 5th experiments not registering.

I feel the following two situations (see screenshots) should be the 4th and 5th ethically questionable experiments:

-zapping grunts (both human and alien) with the second ray emitter in the cryo-chamber

-gassing the headcrabs
*Do you have to enter the chamber of headcrabs and return before gassing them?

I wasn’t smart enough to find the missing 2 experiments in QE either. :frowning:

You missed the [redacted]-cannon, for starters! It’s early in the level, I believe after the second experiment you listed.

So which experiments are the 4th and 5th?
Are they just not registering by me?

So apparently the 5th experiment is firing the laser with the shield down, frying the caged headcrabs in front of the shield.
This also did not register as an achievement in my playthrough.

oh… same
