Positech Games are looking for people to beta test the upcoming Mac version of Gratuitous Tank Battles. If you like tanks, battles, and Macs, then this might be just the thing for you.
There’s a catch though; you must already own the Windows version of GTB, and must have bought it directly from Positech. So I’m guessing that rules a lot of Mac-Tank-Battle-lovers out then. On the off-chance you fulfil this criteria, see the instructions via this link.
