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

The best way to win this is to camp. And the best place to camp is the parking tunnels, not the bigger one, those little rooms without doors. While you hide there, PLENTY of Venus Starrs will come in hungry for your blood. Don't give them what they want - use the Rocket Launcher, as it results in a bigger explosion than the Homing Launcher. When giant groups of Venuses show up, fire into ground at their feet. If you die, just go to another tunnel and resume. Don't forget to gather extra ammunition whenever you can, as running out will prove somewhat fatal. It's possible to get a platinum using this strategy.
