Besides putting much of its catalog on sale SEGA is giving games away completely free on Steam.
The first “Make War Not Love 3” prize bundle includes the HD remake of its still gorgeous Jet Set Radio. In addition installing the pack will gift you with Golden Axe, Hell Yeah! Wrath of the Dead Rabbit and its assorted add-ons, as well as a collection of Genesis games.
To unlock the games all you need to do is head to the event’s Steam page and click “Install Game.” It’s worth noting that this seems to be different from the storefront’s free weekends, during which specific games can only be played for a limited time.
