This is T-17 Tanky. Watch its trailer above. You'll either scrunch your face up for a second before turning it off in disgust or think, my God, where has this game been all my life.
There's a slight Cat Shit One vibe to proceedings, but in general, it's just Battlefield. With only vehicles. And driving the vehicles are adorable little cartoon animals. And it looks a little more serious than DICE's series. Here, let the game's official site describe things:
T-17 Tanky is a game about shooting at distant things. You are a bird that drives a tank. You must kill foreigners who want to take your melons.
That about does it. You can play a rough early demo here if this tickles your particular fancy.
