Well first of all about Spies, when i saw few gameplay of them. at start it was not so cool, but after watching those videos 5-10x times it gives some sense. ^_. Nightvisions r more realistic now, which means that if you get torchlight to ur face while you got Nvg on ull get ablind, but not sure how long ull be blind cuz of the light+nvg on.
Thermal visions, r also pretty realistic this time also, cuz thermal vision spots only moving merc, and if hes not moving, ur thermal vision dont detect him so easily cuz of heat.
About Merc drones, they can be rly usefull, but i wont use it cuz of risk being necked... and it gives feeling like using camnet what i hate in this game. ^_
I hope mercs weapons like / those Rfiles,Uzis... 'i think' r change it abit more powerfull this time, cuz spies r like monkeys in this sc 4 versus.... so i would like the idea that if spie gets 4-5 shots... spy will get down and die, not like in scct... u need about whole uzi magazine for example to kill the spy IF u dont spray spy head,
But yeah, i cant wait this game >_< gonna be awsome.
