Full playthru of the game on Easy Difficulty with timestamps in the pinned comment for every secret weapon, weapon mod station, and encyclopedia entry in the game, plus how to get some of the other achievements. Most of the others not covered are self-explanatory, but a reminder that you must start a new save slot when attempting wither the Purist (never mod a weapon) or Immortal (beat the game without dying) achievements. Therefore, you may not use NG+ when trying to get the Immortal achievement.
Some of the Encyclopedia Pickups are not always represented by the floating white squares, and can refer to entries that you can miss while going through your normal game progression.
Another reminder that the key for the Super Shotgun disappears if you use the Chapter Select screen, so if you want to come back to The Diplomat to get the final Encyclopedia entries, do it after the game ends like I did in this video. You can also start a game from chapter 4, pick up the key, open the console, and then use the loadlevel console command to jump to Chapter 12 to speed things along if you missed it. If you want to be really cheap, you can get a lot of achievements by using the console, but that's no fun.
