I have a suggestion: You should grunge up those levels. They look a bit too... clean. Like after every match a cleaning guy comes out and wipes everything up. You should add dirt layers and grime to the levels, add some graffiti and debris, etc they'll look way better :)
One of the best racing games I've ever played. Feels just like something I'd find in an arcade. Works almost perfect with a Logitech Extreme 3D Pro Joystick, which only enhances the near-perfect arcade feel.
@hojoon: Please be patient. The UMP45 Has not been added yet (the fact that it is in server settings is a bug). We are awaiting art content before it is finally added to the game along with other weapons. Be patient until then ;)
For everyone STILL ASKING ABOUT THE MP5: IT's NOT DONE YET!!!! IT"S STILL BEING DEVELOPED! THe main roadblock to completing it is actually art resources, since OnMars currently does not have a dedicated character modeler and we can't keep using models from CounterStrike. I think if we can find a decent 3D modeler/rigger/animator, the MP5 should come out fairly quickly. Until then, be patient!
Also, to add to the CoD argument, CoD doesn't suck by itself (really, who the hell cares about storyline? Quake sure as hell didn't need story, and it's still awesome to this day), the main issue is that it has remain largely unchanged, as Treyarch is pretty much playing it safe and not breaking into new territory. To be a great game, it really needs to change and evolve instead of being the same game with new graphics every time.
