There seems to be a problem with where the bullet lands when ADSing. With enough distance, you can see that the bullet lands at the "peak" of recoil when ADSing, not where you actually aimed.
tl;dr? The bullet lands above where you aim when ADSing.
My biggest gripe with the manual weapon switching mode is you throw your knife and have to reload it! While in the automatic weapon switching mode, the knife is resupplied instantly.
The acceleration of the car is weird. It accelerates faster at the high RPMs than at the low RPMs. The best example of this is the Catamount stock. It accelerates slowly from 40-45 and then the acceleration suddenly spikes. Why is that?
I want to upgrade the fortress! Seems like a useless building in terms of resources; it just sits there, consuming energy and producing waste and smog.
Browser FPSes are impractical. Stand alone versions such as Combat Arms, AVA and Crossfire can achieve a much higher FPS because there is a more efficient engine than Unity. My comment on the map, too many objects on it.
