Also, Assault adds the strategic element to the game which Quake3 Arena lacks. The bots in Unreal Tournament are very smart, and their AI can be adjusted. They can be anywhere from Novice for the newbies or Godlike for the veterans. You can even give them orders, which vary from each gameplay mode. Most of the times the bots will do what you want with some logic, but on rare occasion they may not do exactly what you ordered them to do.
All weapons have two firing modes, which each do something different.
With primary fire it will fire a mini-nuke in a straight line and will explode on impact. But hit secondary fire and you can actually guide the missile to it s target. It will even lock onto targets for you and highlight them while you re flying it to find the enemies more easier. Once you find your target, land it near him and it will create a large blast radius. The graphics were very nice.
