I’ll go first:
This was a game that was included as a shareware on a Swedish PC Gamer demo disk back in the late 90s/ early 2000s.
A 2D game, with a side view, where you play a spaceship/fighter jet that begins each level above ground. You fly into a base, defeating turrets and other fighters while going deeper down into the center of the base. At the center of each base you find a reactor core.
When you find the reactor core, you attach a cable to it, and your mission is to make your way back out of the base to safety while tugging the reactor core with you. During this, a timer starts counting down until the base self-destructs, so you have to scramble to get out while wrangling this heavy, dangling reactor core while navigating back through the base.
This was NOT Descent, even though it was probably inspired by it. As I mentioned above, 2D, side-view.
