Here is a sandbox like no other. Create massive battles with absolutely no limits. Want to see 10,000 chickens fight an army of Romans?? Sure, why not. Want to see a company of WW2 U.S soldiers fight 11,000 Medieval soldiers?? There are simply no limits to the carnage you can achieve in UEBS.

Both games are Windows-only.
They were giving out UEBS for free in January and even then it wasn't worth playing. The "gameplay" was amusing for about 5 minutes before it got repetitive.
Unfinished and they're already working on UEBS2 without finishing this game. I'd avoid this developer/publisher altogether.
