Warface is a bad game.
Like most F2P games, you'll need to make an account. No big deal, just a hassle. You also will have to put up with Warface using its own independent launcher, which means it updates outside of Steam. When Marvel Heroes has shown that F2P games can update from the Steam platform with few headaches, it's hard to give launchers a pass anymore.
Anyways, the game proper is very fond of its status as a co-op focused FPS. And Warface is, in fact, a co-op focused FPS. On the surface, it looks like you have a great new game for you and your buddies. Each day, a new rotation of missions is put in play, requiring you to complete the lower tiers of dificulty before the harder missions become available. So you'll do some mindless shooting, then get down to more objective based missions, and then get your ♥♥♥ handed to you in the highest tier content. Fun, right? No. Not fun. Don't you ever make that mistake again.
The thing about this content "climb" is that there's no matching progression on the player side. You'll easily complete those first two missions each day, and then naively jump into the newly unlocked mission only to get absolutely slaughtered. You might make some progress, but eventually, there's a point where the game reminds you that you aren't using the "cool stuff" yet, and will have you looking for the "quit game" button.
On top of its hamfisted attempt at forcing players to spend money to have fun, the game doesn't always tell you the whole story. When you first start the game, you get a message saying that you can do a quick tutorial, and as a reward, they'll give you a free gun, a pair of gloves, and some in game currency. Having played the game in an earlier beta, I jumped on that offer.
Of course, after completing the training and looking at my inventory, I discovered that both the gun and gloves were set to expire in 24 hours. Nowhere did it tell me that beforehand, and they had never said it'd be a permanent reward, but it still comes across as gross and impersonal.
There are four classes in Warface, but for some reason, the devs have locked two of them away until you reach certain points in your ranking progression. This is great, because every match needed to be nothing but guys with sniper rifles and M16s. Who needs medics and engineers? This wasn't the case in the earlier build I played, and is a mindboggling change. Do they think players won't understand how the complicated mechanics of "equip this, click to heal" work?
There is PVP as well, but it's an afterthought that you'd be better off ignoring. Honestly, I suggest you ignore this game entirely. Everything is designed in such a way that they hope you'll be tempted to open your wallet (Hey, you may be dead, but if you spend some money, you can revive yourself. Blatant disregard for our own games design is meaningless when it means making a quick buck!), unlocking new guns, attachments, and equipment is both luck and a grind. You have to select one of the three you'd like to work towards, and you can't choose which item in each you are working for. So if you don't want that sniper suit in the outfit section, well, it's going to stay the only thing you will get from outfit until you give up and unlock it over something in weapons or attachments. Great.
I had last played Warface during the closed beta, what feels like a year ago now. With the release on Steam, I was surprised to find that the game has actually actively become worse. The developers think you are an idiot, and will spend money at the slightest provocation. Don't prove them right.
