IGN: Red Dead Redemption: Liars and Cheats Preview

IGN writes: "Cannons are a bitch in Red Dead Redemption: Liars and Cheats. Yes, I know most of the buzz about this pack of downloadable content has focused on the exploding rifle — a firearm that blows whatever it hits to smithereens — but after playing yesterday afternoon, the cannon is all I can think about. More specifically, it decimating my team and I while we tried to take a base".
