Spoiler

At the moment this is only coming to China in 2016, but Tencent do operate in the west. The game will 100% be free to play with microtransactions, and if you want to get it your best bet will be to download We Chat on your smartphone. I'll try to figure out later how it can be played overseas and update here if it's possible. At best it may require me to send some invitations to the game to your phone or something, which is how I got Thunder Raid.
Otherwise it looks far superior to Contra Evolution, which was also by Tencent and was an awful mobile Contra remake released on phone and arcade simultaneously with no discernible differences. Basically it was a phone game running on an arcade machine. I took some video of it in the local arcade and it's truly horrendously bad.
The biggest problem I see with this game is playing Contra on a touchscreen, and I have no idea if it will respond to micro-USB pad setups. Otherwise it looks kind of ok... except lifebars?
