Bass should have more attack and needs maybe some EQing.
I like the main melody synth, it has an incredibly good melody and a nice flow, well placed filter sweep.
the samples are a slight bit too dominant, though well panned.
in general your percussion is a bit too static. First of all you might need better samples, but you can often compensate that through multi-layering your drums.
I dont like the breakdown gated 303 synth somehow.
That buildup and intensity increase with the "ludicrous" and "holy shit" is well thought. As said, do some level adjustment there.

Ok that being my points of criticism and first impressions. I'm an UT2k4 player and I think your track suits the game and its feeling very much. In addition to that, it has a nice flow and buildup. the main melody is just focking well done ... I have to say I enjoyed listening very much

thats it, hope it helps

Awesome, thanks for the tips! I'm growing more and more aware that i need better samples, hehe

That's pretty cool. I recommend adding some other background synths (maybe filtered or gated) that either support the main melody or harmonize with it (will add a feeling of complexity). I think this because the main synth is pretty straight forward. Other than that, I'd say that's some pretty good work.
