Hey, you! Yes, you! Do you like games? I bet you do. That’s why you should drop what you’re doing and grab a free Steam key for Stellar Impact on Green Man Gaming for the next few hours or until supplies are depleted.
The digital distributor is having a timed sale, which it already used to cripple its servers for days now, so you may have to retry a few dozen times before getting there. You have until 10PM GMT. Grab your free copy of Stellar Impact here.
Failing that, the site still has its regular sales up and those include XCOM: Enemy Unknown for $12.99. You should probably grab that one too, now that you’re there. Darkout is a pretty atmospheric alternative to Terraria too, should you really get lucky with servers.
Update: Playfire mentions that they’re out of stock. Regular sales are still going though, so go get those.
