Humans, the Marines, the space cowboys, post your ideas here regarding the human race. My idea would be to have a more complex specialisation system, like an engineer, medic, soldier etc. I would also like to see maybe a sprint mechanic and a much better flamethrower, a more sexier flamethrower. With beautiful flames. And for some of us who can't make our own skins, be able to purchase cosmetic items from the in game shop.

for the human race, the armor or jetpack choice was a tough one but I'd like to see sexier versions of the suit and jetpack. Maybe have even more guns like a grenade launcher with different nades to pop. E.g. smokescreen, frag and stun grenades.

maybe add night vision, thermal vision goggles.

That is out of theme with this particular game.  Players will be able to retool using an armory of some sort to change primary devices, rather than joining a dedicated class.  This allows a lot more freedom within the game, and makes for a funner, more unique experience.

All of those are already going to be implemented.

I think Robots would be a great idea. Robots not computers.

Oh good, I'd also like to suggest a "push and block" mechanic not unlike avp and left for dead to give our human people a good fighting chance against the marauder bites and tyrants etc.

Maybe have a sexier battlesuit and make the player taller when inside, as in heighten the eye level of the player when inside to make it seem more realistic. Idk but the battle suit should give the player some degree of super strength, like rip off an auto turret and use it. Sorry, been watching Schwarzenegger throughout my weekend...
the inside of the battle suit helmet should fog up from the players breath when inside, and some dynamic lighting to make it sexy.
