Cliffhanger Productions announces Ærena: Clash of Champions is in early access on Steam for Windows, though OS X and mobile editions are also planned with cross-platform play promised. They call this game a "Tesla-meets-Dr. Frankenstein dieselpunk" conflict for Æther (our vote would be Unobtænium), showing their commitment making this game difficult to Google, though Steam just ignores the issue by listing it as "Aerena." Here's word on the game:

Ærena: Clash of Champions features true cross-platform gameplay across desktops, mobile devices, and browsers. Whether playing solo or against live opponents, players can command their teams of gladiators to outwit, outmaneuver, and outgun their opponents from virtually anywhere.

In the deadly confines of the arena, every action is a tactical decision. But, there are no winning formulas. With the option to recruit new gladiators and customize the supporting abilities of your ship, your strategy is your own.
