A few days ago, Developer tinyBuild issued a challenge to their Twitch following. If their Twitch chat could beat them at their own game, One Troll Army, they would release the game for free. Welp, tinyBuild has found themselves eating crow (though I'd imagine they planned this all along) as One Troll Army will officially launch for free tomorrow.
One Troll Army is a Tower Defence game where players control a single troll and defend their base from a horde of minions. You can build up your fort, upgrade your troll's abilities and customize its appearance to have "the latest in troll fashion".
