Been playing it for a while, this game seems to have so much potential but ultimately the infantry combat is annoying.
The game has no stamina and infinite sprint, you can also hop around as much as you like so you can guess how farsical the infantry combat looks, its more of a game of who can hop about like a tool and get a few lucky hits in than anything. Imo the infantry combat also feels a bit "floaty" as well.
For some ultimately retarded reason any armoured vehicle gets affected by almost every weapon, if theres a tank driving by you can shoot it with a pistol or smg and it does damage, the damage a smg does is pretty extensive considering its firing bullets, about 2 magazines laid into a titan tank can drain maybe a quarter of its health bar. Same thing for the strogg walker etc.
The vehicles are pretty ok in the way they handle, theyre not really what i would call battlefield like. You can knock wheels off apc's etc to disable their movement..at least when you're just messing around in spawn, in game as of yet ive yet to see any vehicle get its mobility disabled, people just seem to go for the kill.
The one feature i really like about the game is the anti personnel\ anti air\ anti vehicle structures. Initially they can only be around your base but when you take over other parts of the map you can plonk them further afield. Its something new to this kind of game and something that obviously battlefield has never had. Theyre totally self automated so no need for someone to sit in one for 15 mins guarding an area.
