There's 1v1 dueling via the clan dojo system now.

And there's no real "BPO" item, it's just many items can be purchased with real money, but every one of those items can also be purchased via in-game money or you can purchase/find their blueprints, which just means you have to spend additional credits/resources/time constructing it. Literally the only things you have to spend real money on are cosmetics (some of which are offered for free occasionally like holiday color packs and weapon skins via their alert system) and additional frame/weapon slots (which you can buy some with your small amount of starting platinum).

Kinda reminds me of Too Human for some reason... not sure why. Maybe mixed with Gears of War.

TL;DR

I saw a game, it looked shiney, I've not played it, it's better than DUST514.

I've been playing Warframe for months. I know exactly how it all works. You either buy the suit for platinum or you buy the blueprint for the suit with credits, which you then have to construct from components (which includes farming for 3 other blueprints which have to be constructed when it comes to building a suit the free way). I'm just saying it's not analogous to the BPO kind of idea because everything is infinite use (weapons and frames anyway, the blueprints themselves are consumed in construction and there are some ammo/health consumables).

That video is old enough, though, that the skill system shown is very different from what it is now.

Edit: This is what it takes to make that Rhino without spending real money: http://i.imgur.com/YCIEoS5.jpg

The top is the blueprint you saw for what's 35k credits now. The bottom 3 are blueprints dropped from one of the bosses. Build the bottom 3, then combine them with the purchased blueprint, then you have the exact same item as someone who bought it with real money.
