I've been combing through what is enjoyable to do in terms of 'out of story' missions in GTA: Chinatown Wars, not taking into account finding all the hidden cameras or unique stunts, which I probably will not go after. Here's the rundown so far:

• Story missions complete (duh);
• Firefighter Missions - GOLD MEDAL, thus unlocking 'fire proof', which speaks for itself;
• Mail Delivery Missions - GOLD MEDAL, thus unlocking 'bigger pockets' for drug carrying;
• Noodle Delivery Missions - GOLD MEDAL, thus unlocking 'marathon', giving me infinite sprint;
• Taxi Cab Missions - GOLD MEDAL, thus turning all cabs bulletproof;
• Vigilante Missions - GOLD MEDAL, thus giving me double armor points;
• All 21 safehouses bought, earned off a random person's mission (Wilhem) or won off lottery scratch off cards;
• All 80 drug dealers found;
• 2 golden lions found, thus unlocking both Xin missions;
• Both bonus 'Xin' missions finished - great little mayhem situations, by the way;

I still have to find the gun club and get the gold medals there too, then I might be giving this one a rest.

Oh, and a note to all cops in Liberty City P.D: stop running over my accident victims while I'm trying to pick then up. It's annoying when I'm on the 14th pickup in a 15 pickup run, OK? Thanks, jerks!
