Paco Loco is the penultimate boss from Sunset Riders. One of the three henchmen of Sir Richard Rose, he protects the dam which give access to Richard's mansion, shooting anyone that gets near, having a bounty of $70.000 over his head. The four bounty-hunters Steve, Billy, Bob and Cormano fight him in the dam, defeating him then exploding the dam to enter Richard Rose's property.

Paco Loco is not hard to defeat, despite being a late boss, as all he does is stand over the dam wall while shooting from his minigun. He is aided by a goon hiding in the tree in front of him, who will constantly toss explosives at the player, so it is advisable to kill the goon as soon as possible.
