I am not sure, but I think it is a Mac game from late 90's - Prime Target, or something similar

Is that the Build engine?

You are most certainly right, Amok! And to answer your question, FraterPerdurabo, it actually runs on the Marathon 2 (M2) Engine, which Bungie Studios made for the two latter installments of their Marathon trilogy. It's also used by such games as ZPC, which I'm sure most of you know of, and Damage Incorporated (Or Damage Inc.). Both of which are FPS games from the mid to late nineties.

If it is Prime Target it uses an improved version of the Marathon Engine (I think the engine has the same name as the games). However, there are no screen shoots on Mobygames, or any other gamesite I can find and trust, so have no evidence.

Edit - Ninjad...
Anyway - I had prepared the next one. It may or may not be very easy.

King's Bounty

ohh - that was quick, and correct. Your turn.

Easy one

Future Cop: LAPD?

Yes it is ;)

Cool.

This is an easy one, but the picture is a bit weird so might make it more of a challenge.

Soul Blade?

If I got it correct, here is my riddle:

I am going to sleep right now, so if anybody's 100% certain about the game title, just guess and post your image without my confirmation.

MediEvil 2

I'll be posting the next game in a couple of minutes. I need to find a good one first. ;)

Edit: Found one. It took me a while to even remember the name of this game. I'm sure some of you do know this one.

"This ist a training area!"

Loving the typo there, lol.

Nah, its just German :)

Sorry I'm a bit late. Yes you were right, of course.
