Steam News announces that Jump Tanks is now available as an early access title, offering five-on-five armored team combat, though they don't use the term MOBA in describing this. Here's what they do say about it:

Humanity is in a precarious state. Radical factions squabble over scarce resources, and the best way to earn a day’s rations is to own an armored jumping tank. Luckily, you have three.

Jump Tanks is a online multiplayer combat shooter where it's us-versus-them until the battlefield is littered with broken machines. Prepare for explosive, frenetic matches where you'll dodge rockets and pounce from rooftops through storms of bullets.

Build your Battalion
Customize three different tanks to take into battle. Don’t like your gun? Pick a new one. Need another jump to get the drop on the enemy? Swap in different legs. Millions of custom tank builds await you.

Each Battle is Personal
Coordinating with your teammates is crucial to gain an edge over your opponents. Stick close to your ally to earn a special buff. Avoid your rival, who has an advantage over you.

The future may look grim, but with you behind the controls and your team by your side, there is hope. See you on the battlefield!
