Continuing from the old topic to give credit to the finder of the first game I was looking for.

The game I am still looking for and would really like to find:
An old RTS game with two factions, a red and a blue faction. I used to play a demo and a full version, the game contained cheats and the red faction had these AT-ST kind of walkers. It had a campaign mode, although I am not sure of a skirmish mode. It was around the time of Commandos 1 that I remember playing it and it should be from around 1998 as I remember playing it on Win98 and I remember the year in which I saw it. The interface is placed on the right side of the screen.

I hope this information is sufficient to get some game titles rolling, an I thank you in advance.

Already Guessed:
7th Legion
Dark Colony
Z
Gender-wars
KKND krush-kill-n-destroy
War of The worlds RTS
Total Anihhilation
Elite

Westwood RTS
Star Wars RTS
Exterminate
Warzone 2100

--List gets updated when possible--

Did it look anything like with walkers like [url=http://www.youtube.com/watch?v=kHdsci3_8Hs]this?

I forgot to mention no Westwood games, no Star wars games. I am known with these types and I have done research before posting here. With that I mean looking for RTS games from that time and manually checking them all.

I found this one RTS called "Dark Reign, from 1997 I think. I can't find good screenshots featuring walkers,though, but it would seem there are two factions, red and blue.

Available on GOG too :)

3d or 2d?

Outpost 2 maybe?

It should be2d, outpost 2 is not the game but the font is about the same style I think.

i am browsing through this..

Do you remember the color of the terrain perhaps what the setting was?

Dark Colony?

I too think Dark Colony is it. Interface on the right, Red V Blue.

One of the last really hard RTS games: http://www.youtube.com/watch?v=I-Axq4wFBms

Did I mention Dark Colony was guessed in the first post? I know Warzone 2100 and Exterminate looks like Total Annihilation. It might really be an unknown game, but I am 100% positive it exists. Please read the already guessed games before posting. I really appreciate everyone thinking and helping out. But I feel really stupid when I have to tell people it is already guessed or a pretty known game/series. It was green if I recall correctly. It looked like it's from this time. But there were alot of futuristic 'like' elements in the game mostly in the red side if I remember. Reffering to those AT-ST like walkers again here.

There's no need to feel stupid. The first rule of tech support is to assume people don't know anything if you can't be sure that they do :D
