Rocket Man is an Arcade League game. Not the hardest one, but takes a lot of skill and speed to get gold. And to add on, the only weapons are rocket launchers and homing launchers!

Briefing

Sergio loves to visit the Streets at night! He relishes the feel of the cold snowy air gusting through his loincloth as he scampers up and down. But most of all, he loves to show off with his rocket launcher in front of all the lovely ladies.

Strategy

Load yourself with the rocket launcher, not the homing launcher. The rocket launcher can shoot 3 rockets out making it easier to get 40 kills. Another good idea is to fire into groups of enemies, it'll save ammo and get more kills.

Remember, to get gold, you need to kill one person every 2 1/4 seconds, which makes the game even harder.
