So Kazz and I have been messing around with,
Airmech and it's pretty cool.
It's that new online version of the old sega game Herzog Zwei. You can play 1v1 like the old game or teams of 2v2, 3v3, etc. Also, you get to pick your unit load out. So you can go say, assault heavy or defensive or money making heavy, just whatever units and other things you like.
Also there's lots of different "airmechs" that all have different stats and capabilities. Pretty much all of them shoot with left click/trigger and then they have some right click/trigger ability you can level up. For instance, the helicopter fires missiles and the default plain looking one has a beam sword and shield. They all have a couple of passive abilities that make that airmech feel different than the others as you level them up too. Like, the helicopter gets better at carrying things and has armour upgrades where as the plane gets increased damage on it's attacks and takes reduced damage from attacks at the cost of energy instead of health with it's energy shield, stuff like that. The Saucer has a teleport move and there's a bomber looking one that can't shoot other airmechs when it's in the air but instead drops bombs so it can attack grounds units with impunity.
It's all freemium model too where you can earn access to non basic units and airmechs with "kudos" or real money. Oh also, I like how in your "army" you can pick things that aren't even units to be able to build. There's things like rocket boosters where you build them and then pick them up like you would a unit but they just make you fly super fast until they run out or you drop them and similarly, there's bombs you can build and then just drop on things.
There's lots of different kinds of "infantry" too. They all capture bases but then their other capability is different. Normal soldiers shoot, fixers repair vehicles they happen by that are damaged, there's suicide bomber guys and then there are probes that are just deficated base capturers that don't shoot or do anything but move really fast.
