The Sixth Gun #29 (Oni Press, 2013)

In order to free themselves from the burden of the Six, Drake and Becky must set out on a quest to destroy the weapons once and for all. Even with Gord, Kirby, and the uncanny Asher Cobb in tow, they may not be up to the challenge—especially with Missy Hume nipping at their heels. Unlocking a new and terrifying power of The Sixth Gun, Becky makes a stand against Missy and her minions.
