Rango

You will be on a platform area while Jake is moving around in front of you from the edge. There are 2 main parts to this fight that he will repeat:

While he is still over the cliff moving around, he will roar at you and this is your cue to start unloading into him as fast as you can to get as many hits in before he stops. After he roars, he will then move around and pick a spot to slam his body down against the ground sending out a shock wave around that area. Once you see where he is going, just move out of the way as fast as possible to avoid it. He will then repeat those 2 steps until you've unloaded enough rounds in to him at which time he will just fall over then and be dazed (stars above his head). This is when you really want to lay into him to do damage.

Once he wakes up, he will disappear from the screen and enemies will begin to appear on your platform area. Every so often, Jake will pop up from the ground to do an attack (signified by a circular sand area). Avoid these attacks by staying out of the radius of the sand circle and focus on eliminating the enemies.

After that he will return to the first step again, so repeat the steps there. Once you finish that part, he will do something different in the second half. Instead of disappearing and attacking from the ground, he will put his tail up and start firing bullets at you from it every so often. Stick with the same strategy of avoiding his attacks and focusing only on the enemies.

When that step is complete, he will return to the first actions again, only this time, he will ground slam twice before he roars. Once you stun him and fire at him this time, he will fall and the trophy will be yours!
