HoboTron

Hobotron is a side-mission in Grand Theft Auto: Chinatown Wars. It is located on Colony Island, on the top island. The only way to access this island is by swimming or boat.

Mission
The mission is started by walking into the blue circles in the graveyard. You lose all weapons apart from Fists, and get three timebombs, which are dropped by touching the icon on the touch screen. You can gains weapons throughout the mission, just look for the green dots on the radar.

You then have relentless waves of 'hobos' chasing after you. At the start, the hobos have little health and no weapons, apart from fists. As you progress through the levels, they become progressively stronger and better equipped. Just fight your way through!

Scoring
To score in Hobotron, collect the money the hobos drop. You get more money, depending on the way you killed them, and the weapon they had equipped.

Tips

 * Watch out for the hobos with swords. No matter how much health or armor you have, they normally are one-hit kills, even for you!
 * Collect the money they drop as soon as you can, as it disappears quickly
 * If you are struggling with this, try getting the 'Double Armor' upgrade (by completing 5 vigilante waves with 100% kill rate) and 'Regenerating Health' (by getting a gold medal or higher in both 'Dragon Wagon' noodle run missions)
 * Also, if you are willing to use cheats, all the weapons cheats work, so use these to get the minigun or other heavy artillery weapon.

And finally...
Happy hobo smashing ;-D
