When you ODK a Twisted, you will be staggering for a few seconds after the Dive, which can prove fatal on higher difficulty modes like Genocide. To avoid this, simply dodge roll during the animation to skip it.
Get "Restock" "Healing" DNA skill and whenever your out of ammunition or need life just keep using overdrive until "Restock" or "Healing" skill is activated. Don't worry about getting hit by the enemy since whenever u select a person to overdrive the game stops and you'll be able to divert the enemies attack by doing so.
The Berserker laser gun, used for the fight against the Reaper in Episode 5, has a glitch which has it cause damage while in the main menu.
When a soldier with a Berserker arrives, dive into them, aim the gun and hold square to begin firing the laser. While firing, press start to enter the main menu and then leave it in the menu for a short period of time. Cancel out of the menu after, say, 20 seconds, and you'll notice that something has damaged the Reaper. That something is the Berserker. When you exit the main menu, the Reaper will be damaged for an amount proportionate to the time you spent in the menu - longer time will inflict more damage.
This method is extremely useful for higher difficulties.
