Here's a few working character builds:
Specializing in one or 2 gun types is the most straightforward way to do things. Your starting 9mm pistol is a relatively good weapon and come with a fair amount of ammunition.
You don't need much Strength except for carrying loot, but Agility is mostly irrelevant to this build as you won't pick a lot of locks. And more to the point, combat skills are easy to increase and have only a small influence on your accuracy, so you can counter your low agility with the lockpicking skill (which has synergy with your high Perception.
* Stats * Strength : 7 * Agility : 8 * Perception : 16 * Endurance : 14 * Charisma : 10 * Skill Set - Combat: Mix one short range weapon skill with a long range weapon skill. * Shotgun : 200 * Rifle : 200 * Stealth : 100 * Skill Set - Robber * Handgun : 100 * Lockpick : 300 * Stealth : 100
Melee is cheap, you can allocate a fair amount of skill point to Stealth. All you will need is a good combat knife. Don't forget to corner your target and use the sprint command, otherwise you'll never be able to finish your enemies. Also, don't expect to charge a hostile shotgun equipped cop and be victorious from the start.
* Stats * Strength : 17 * Agility : 14 * Perception : 5 * Endurance : 14 * Charisma : 5 * Skill Set - Pure Melee * Melee : 350 * Stealth : 150 * Skill Set - Robber * Lockpick : 400 * Stealth : 100
Thieves have good odds against safes and are decent pick-pockets, however they don't last very long during a combat. A high charisma allows them to get discounts in stores and pawn shops.
