Finish Temple of Trials

Your very first quest in every new game of Fallout 2 is this one. Since you don't have a PipBoy at this stage of the game, no log is made of this quest, but the only way forward is through the Temple of Trials. The quest, and the temple, are located in Arroyo.

Rewards:
 * 600 experience points for using speech or steal,
 * 300 experience points for fighting Cameron,
 * +15 karma,
 * Vault Dweller's suit and the PipBoy.

You can also earn experience points by fighting the ants and the radscorpions which inhabit the temple and by disarming the floor traps which shoot Sharpened Poles as well as using Lockpick skill once.

The quest itself can be seen as a training quest, as it forces the player to use a wide variety of skills to pass, concluding with either fighting, sneaking, or talking your way past Cameron.
