Shameless copy/paste from their forum where a guy gather all the info until now from developers.
Here's What We've Learned from the Previews
So in no particular order, here's the relevant info gleaned form the half dozen or so previews posted in the Preview thread:
From the Boss of Obsidian, Feargus Urquhart
""And the player's going to have to choose how they want to play, and how they want to improve their vehicles. Ideally, the players that are jumping into these tanks, and different types of anti-tank vehicles, they're going to feel a sense of ownership.""
Extensive "progress" trees.
Multiple tiers of "unlockable tanks".
You start with a "fresh vehicle" and add "different upgrades and customization parts".
Fully destructible environment
15 V 15 PVP mode
Co-op 4 player V AI PVE mode where you compete with the other human players for "points and the like" (whatever that is). PVE will be story driven it seems.
"very complex" upgrade system for weapons and armor
Movement and shooting and view controls are very similar to WoT.
Spotted enemy vehicles have a red outline as per WoT.
Tanks have "larger" (ie non realistic) ammo loads - may be selectable though.
Consumables such as fire extinguishers again like WoT.
Mentions multiple "lives", so maybe respawn or full garage mode
Default view is third person, moving to first person for gunnery, again like..WoT. What else could they do though.
"“We want the PvE mode to be a completely valid way of playing the game,” Obsidian designer Rich Taylor said. “It’s not like, oh, well, you play this first, and then you graduate to PvP. If you want to only play PvE, our goal is to have that be a very satisfying experience with full progression available in it.”"
Health bar, yes confirmed.
Your crew will be "upgradeable" and will "influence your progress", whatever that means, and will be "characters" in their own right.
Mercenary mode, where you work for a private military contractor and unlock the vehicles they are equipped with.Not sure if this is the primary mode?
Your "base", "workshop" or "garage" will be customizable "with structures almost like an RTS" and will have "some effect" on your progression.
"In terms of progression, Obsidian assures that fans of their deep, gear-laden RPGs of past and present should have plenty to work toward."
Armored Warfare is being billed as “free to compete,” with microtransactions probably including the usual fare of XP boosts and cosmetic upgrades. Karabaich stressed the importance of keeping everyone on a level playing field within an actual match regardless of how much real cash they’ve spent on the game.""
"Territory Wars" Clan based mode, similar to CoD:Ghosts Clan Wars Mode
No ponies or princesses.
That's about all I could get from these, please feel free to add anything I've missed or expand on the points above.
So it looks like it will be a WoT with modern tanks and some other fancy stuff.
