- Improved radar
Successfully complete the game. When episodes are replayed, your radar will now display the location of Tech Point Caches, Ammo Caches, Weapons Lockers, and Journals.

- Easy 'The Squishy Center' achievement
Disable the Watcher Archon, then use the melee finisher on its tail to get 'The Squishy Center' achievement.

- Easy 'Big Bang' achievement
Damage a Watcher Knight until blue smoke appears from it. Then, keep pushed a grenade until it begins to sparkle yellow, which means it will explode approximately three seconds after being thrown. Throw the grenade at the smoking Watcher Knight to kill it and get the 'Big Bang' achievement.

- Easy 'Terminal Velocity' achievement
Go to the area where Will first learns to fly in Episode 1 to free fall for ten seconds and get the 'Terminal Velocity' achievement. Notice: To get more distance and a few extra free fall seconds, use the hole to the prison that is the level's exit.
