Freeware shooting game (like "Area 51" arcade)?

Archived from groups: alt.comp.freeware.games (More info?)

Hello.

Is there any freeware shooting game, like the game "Area 51" that there
is in arcade machines?

I don't remember if this is the exact name, but in the game you were
trapped in a military base and had to kill/escape from aliens and other
stuff.
