I played an FPS game in year either 2004,2005 or 2006 (Hence the game could not have been released after 2006). It had three levels or scenarios or difficulties: City/Street, Ship Dock Area and Inside Train. It was on Windows platform.

I do not remember it's name and now willing to find/play it.

Do someone has played such a game?
If yes can I get suggestion towards its name.

Also the game was realistic type game, I mean to say no Aliens, Cartoon character etc. Just a player with crosswire to move on target (target was human character carrying guns in building etc.) with mouse and fire to it.

OK I do know this forum is for Gaming in Linux, but since I do not know the name of game which I have played, probably it may be also available as cross platform, hence may be someone knows such a game. Hence platform doesn't matter, if such game is also available for other than Windows, then also I would be pleased to have its name.

Blood?

Thanks dugan for your suggestion. But if you are talking about http://en.wikipedia.org/wiki/Blood_%28video_game%29, then it is not that game. I have seen the screenshots on Google. There are several non-human devilish types of creatures in it. But the game I played was with human characters only as said in my first post.

Isn't there an Unreal Tournament version that has fighting on a moving train?

Try Smokin Guns and Urban Terror. Also go through the lists:

Thanks 273.
But unreal tournament seems more like a fantasy game. I have checked the screenshots.

Thanks metaschima.
It is neither smoking guns nor urban terror I am finding.
Also I have checked the links.
No success uptil now.

Also before posting this thread I checked http://en.wikipedia.org/wiki/List_of...erson_shooters
for all Windows FPS released before 2006, but I am out of luck until now.
Also Wikipedia list is incomplete.
I am also thinking to check for DOS fps game.

Can someone give me a link/site which gives a complete list of windows/DOS fps games.

There weren't that many DOS FPS games. Let's see now. There were: the BUILD engine games, the DOOM engine games, the Wolfenstein 3D Engine games, and the Quake Engine games. That should cover almost all of them, barring the very few using custom engines (like System Shock, the Terminator games, Catacomb Abyss, and, uh, that's all I can think of).

your description reminds me of Max Payne.

It's a third person shooter game. Well it is not the same game as I played.
But it seems to be a nice game.

Any more details? Was it multiplayer only? Did it have a campaign? What weapons were available? Et cetera..

It could be played by single player or two player at least, one player uses mouse to aim on screen and uses left mouse button to fire, right mouse button to reload.
Other player can use numeric keypad.

For campaign, I do not know what it means in a video game, but if it means achieving a goal, then I am not quite sure.

As for weapon the game starts with six shooter gun. At some place in game player also gets a rifle, may be after some time or achieving a score.
