Vampirella slices and dices her way thru Nazi Bases, Castles, Mines etc and Demon Hordes! Blood! Guts! More Blood! Wearing someone like Lederhosen!
This got abit of flak in the press iirc but was and is still one of my favorites. Basically you run around and murder a whole lot of everything over and over with optional infinite bullet time. Could easily be very repetetive and boring but miraculously not (for me at least) - I think because it hits a combination of level design, length, enemy variation and challenge spot on. Also its sooo cheesy in a good way.
Combined with the fluid controls (despite having no lock on, or maybe thats exactly the reason) and just how fun it is to mince everything and splatter pulp all over the place it just never gets old to replay.
Downside is it still (despite having a steam version now) requires alot of farting around to get a controller working right (no native xbox controller support like basically everything else nowadays since the game predates the console) and it gets increasingly glitchy the faster your system is apparently (game folder system/render.ini syncRetrace=1 for a speed bump).
