You can: 1) chat with the residents of the Huevos! Do not befriend them unless you have at least five points of rapport! They are very cruel and they will send you to the bowels of the shaft. They will give you a quest and you will serve them. They cannot be alive after the game is released. If you disobey them, I am sure you will wish you had listened to them. 2) talk to Pirata Muerto. He is the leader. Take things slow and be polite. I don't think you can hurt Pirata Muerto.
To show up the cool stuff from the conqueror zone and cap level I recommend you to get the legendary cape and the disarmor from the kill 3 or 5 birds droptables. According to the Codex the last boss of conqueror zone is the crop sceptic. It's not the native boss of the conqueror zone (but based on the drops). The \"boss\" is the one you get from the first boss droptable from the first conqueror zone. In cap level you'll have to fight the last crop sceptic. The \"boss\" is the one that drops on the final level. As for the passes, they're very common drops or you could just collect them on the way. No this is not the game cheat.
You can find most of the scans in the already-mentioned chest, but some of the codex puzzles are still missing as well. Either way, the codex is as complete as it's ever been! It's full of VERY awesome new content that's all new to the game. 7211a4ac4a
