My long time tremulous 2 wish (what i restrict as copyright) is to actually change the behaviours of the teams.
At Tremulous 2...
The leaders of terran hedquarters will realise that close combat (like paisaws, flamethrowers, chainguns and close-dealed cannons of lucifer) are the most effective instruments against the invader race. They will equip they soldiers with even more powerful battlesuits and change their attitude of "distant killwhoreing" to effective destroyment face to face. the soldiers are becoming somewhat more rude and barbarian, who are spiritually driven to a supernatural level of consciousness. machines would be included into the battle, close combat armoured automatics to enchant the fragile human body with the strenght of rock and metal! Flexible mecha pneumatics would push the human driver towards the alien scums (pounce) with equipped double painsaws (chomp) and built-in grenade launchers (snipe add-on). temporary short range rocket-jumpers would change the old-school antigrav jetpacks, making the humans able to jump swiftly to unreachable places, and with another load further, boosted from the same position (mara jump). Human leaders will equip their 'low-budget' soldiers with ice throwers that freezes the alien bastards into their place, such as basilisks did that to themselves early on. marines with no proven worth would be able to control only simple kamikaze droids, who, with a small engine of antigravitacion, would attach to any surface and will make them able to do suprise attacks.
Meanwhile, the alien race, troughout the senses of the holy overmind, would realise tha the aliens effectiveness is mainly about hiding, suprise, rape and camouflage. the UpperIntelligence will decide the further ways of alien evolvement, so aliens will turn into hiding, sneaking and long-range masters of killing, against the blood-thirst of hummies driven by their blind frenzy. the Mind Over Us will upgrade your zap and split so deadly that any unmechanised human will die from your instant method of turning your slime fluids into deadly acid sprays (flamer, shotty) or projectiles (mass splitter).
I don't want to make any more examples, i guess the idea is clearly shown:
to make humans the melee barbarians and aliens to smart long range nobles, with just as much interference as tremulous 1.1 did... but... mirrored.
I'm already working on this project with a couple of forum and dev people, and it will be ready and playable next wednesday.
