I am trying to remember the name of an old PC game. Came out around 1994, was set in space, on a fictitious planet. You wore a helmet you were not allowed to remove or it would explode. You ran around in FPS view, doing tasks to fix the station. You also went out and fought these terrifying large space bugs. I bought it in a multipack that came with Spaceship Warlock and like 3 more games. Please help!

...spoilers ...

It had a twist ending where you finally had enough and removed your helmet, and found out it was not a desolate planet, and there were no bugs. It was a sunny happy place, and you've been slaughtering the peaceful bunny like aliens this whole time.

Edit- found it. Called Quantum Gate.
