- Borat reference
Shortly after you get the RLS-7, you will cross a footbridge. This bridge overlooks a highway bridge where some enemy soldiers are fighting giant mutant spiders. Use the TDM on the other side of the footbridge to revert the lockers in the room. You can find a note inside one of them that reads: 'My neighbor, he is pain in my assholes. I get a bear made of fur, he must get a bear made of fur. I get a can of meat, he must get a can of meat. I get an E99 technologies... he cannot afford. Great success!'

- Easy 'Mother My Brain Hurts' achievement
While on the freighter, look for a weapons locker next to a watertight door. Locate the control panel that is in the same room and opens the next door. Equip the Dethex Launcher before using the control panel. Jump and use its secondary function to place a guided grenade through the grate maze in the wall and floor of the room. Explode the grenade to open the locked watertight door. There is a weapon tech pick-up and message inside that unlocks the 'Mother My Brain Hurts' achievement after it is read.
