If you're like me and have a addictive personality, mobile games only add to the fire, especially if you're into collection-based RPGs. Gamevil seems to fill that niche to a tee as they continue to release various RPGs with intriguing and entertaining gameplay mechanics while sporting absolutely gorgeous artwork.

Knight Slinger is the next one in their extensive catalog. While it has been available for a little while now in specific regions, Knight Slinger will be hitting on a global level by the end of the month. In celebration, Gamevil is opening a pre-registration program for those looking for an incentive to jump in early. By simply registering your email, you'll get the 4-Star Warrior Sierra, 100,000 Gold and 100 Stamina. In addition, if you post this on Facebook, you'll also get 100 Stable (in-game currency), provided you're within the first 10,000 participants.

Throw your allies around the battlefield and do as much damage as possible on November 29.
