For this weekend ONLY, get the full version of VoltAge:Genesis for 70% off (it hasn't been this cheap since the original release)! For just $1.20 US, you get access to a sprawling open-world RPG with an average playtime of 20+ hours! There are more than a hundred quests to complete, a dozen characters to recruit, and multiple endings based on decisions made throughout the game (none of this "press A to be evil" nonsense).
Download it today, but be careful out there...the Deadlands are a dangerous place.
