We here at Pathea Games are almost at the alpha v0.1 milestone for Planet Explorers. Originally, we'd planned to do a closed alpha to test out everything internally before letting everyone try it out in an open beta. But so far, we feel our current build is already strong enough to be publicly play tested, so that's how it's going to be. We'll put the alpha build 0.1 on Desura over the next few days (after we fix some bugs) and continually upgrade the alpha over the summer until we hit beta.
So, watch this space over the next few days for Planet Explorers alpha news!
