Killer Instinct fighter Thunder is now available for free as part of Double Helix Games' rotation.
It follows the first screens of incoming Killer Instinct fighter Spinal. Hit the link to see them.
Killer Instinct started off with Jago as its free character, then Sabrewulf and now Thunder. The rotation means everyone can eventually try each character for free. Spinal isn't in the game yet, but is on his way.
You can currently buy all eight Killer Instinct characters for $19.99 / £16.99 / €19.99.
