I remember playing this a lot at my local lan parties, but iirc there wasn't too much depth to it...
I'll probably buy it anyway for old time's sake :)
There were a few crafty things that you could do from what I remember. Trying to not get run over by other vehicles was a pretty big part of the game too :P

if you do buy it let us know how active it is online.. or anyone at all who plays this for that matter

I have went to FilePlanet and downloaded the patches for this game, but when I try and install them, it keeps asking for the CD. Any sugestions?
I also downloaded 2 new maps for the game there also, so it wasnt a total loss.

VERY shallow. I would say that this is unfortunately a prime example of a game that should not be included on GOG - a game with no modern relevance, distinguishing features, or popular nostalgia value. I'd much rather have them include more "flawed" titles that were at least ambitious in some way (Messiah or Republic, for example). One assumes Mobile Forces is here as part of a package deal with Kalypso along with Rage Software's other games Incoming and Expendable (both much better inclusions, IMO).
GOG usually includes the latest versions of their games. Is Mobile Forces not already patched?

I bought this as part of the rage promo here along with incomming forces....im enjoying it alot so i think it definitely deserves to be here..i see alot of touches in this game that other games didnt do till years later...The weapons are very basic looking..Kind of a cross between Quake two and Deus Ex weapons..but personally i like that...its kind of nostalgic...The engine works flawlessly....im finding the contols alot more intuative than even half-life/counterstrike. I only just saw that it cmes packaged with a fully functioning level editor....i would love to try this online but i doubt i could find anyone..but at least im enjoying the single player....it has the pacing of Unreal with the gameplay of Counterstrike..

An old post, but there isn't much life on this board, so I don't think anyone will mind.
I've been having quite a bit of fun with this game (albeit in single player, with the occasionally quirky bots). If you enjoyed the original Unreal Tournament and wish that it was mixed in with Counter Strike and a healthy dollop of vehicle action for good measure, then this is your game. It's streamlined (there's a damnable term), but in a good way. Vehicles handle like a dream and the on-foot action--well, it's Unreal.
There still seems to be some sort of community online, though I haven't checked it out in great detail:

Unlike the quoted user, I do believe the game is a worthy addition to GOG, precisely because it was one of the first to actually make vehicles an integral part of gameplay. That makes it relevant from a game historian's perspective, and is also the game's most defining characteristic (natch). The continued existence of an online community, even though exceedingly small (from what I can gather), some eight years after release, would also suggest that it has some nostalgic value as well.
I would also second the opinion expressed in one or two of the user reviews here that this game seems like it would be a blast during a LAN party, and it's certainly small, solid, appealing-looking, and--most importantly--fun enough for that purpose.
And it's a fun way to kill some time in single player, too.
