Old PC game memory?

[DJ Tara-san]

Last night as I was going over some fond 32 bit memories with my husband He brought up the topic of Commander Keen and suddenly I recalled playing a space game but, alas! I have no memory of what it was!

All I remembered of it was that the guy on the cover was taking down an alien with a plunger and in the game it was 32 bit graphics with a 3D-ish setting, the energizer bunny going by at times, and the fact that my PC at that time had trouble loading the maps so I kept getting killed by some small laser-wielding robot?

If anyone can help me recall what this game was I would really appreciate it.
