Easy difficulty is Ghost Babel with training wheels.

• More resources spawn

• Some bosses become easier

• Snake is built like a tank, needing a ration is fairly unlikely.

• Fewer guards and cameras

• One of the awkward aspects of Easy is that Alerts and Evasions clear faster than other difficulties.

• Guards without body armor die in 1 bullet, 2 bullets with body armor.

• Guards will die if you triple punch them.

• Differences are irrelevant compared to Normal.

• Do a one punch buffer to get past the guard in the first screen of the fortress, like on Very Hard.
• There is no guard after the Chris codec.
• There is no guard before the ID card truck.
• You'll need to equip the ID card due to the lack of alert opportunities.

• First screen's margin for error is gone due to the top guard being absent.

• There is one fewer turret before the chaff, but isn't worth the trouble picking up.
• Oddly enough, the screen after the first dogs screen has more guards than Normal difficulty.
• If you are confident in your play, skip the rations near the end and pick up the ration in the first screen of Stage 09.

• There is no camera at the end of the first drop, meaning the margin of error or need for a camshot as a back up is gone.
• There is no guard in the room after the ID card upgrade.
• There is no guard after the blue box drop.
• It takes multiple grenades to bring yourself near death before the death abuse. This is where Snake being a tank becomes a liability.
• There are no guards after the double camera screen during the C4 run.

• There is no guard at the basement elevator, so use a stun to open the doors.
• Marionette Owl does not speed up after being shot the first time, requiring a different approach compared to higher difficulties.

• There is no guard after the vent crawl.
• There is no guard in the ID card room.
• You still want to camshot to avoid getting shot by the one turret after Nikita skip.
• The fast alert clearing makes the second Nikita skip awkward.
• Pyro Bison has less HP.

• There is no guard in the gas room.
• There is C4 in the topleft corner of the Bison room.
• There is no guard in the East wing of 1F.

• Havoc helicopter does not shoot for long when on the West or East sides.

• Kill the guard after the Nikita, remember they take two shots.
• Pick up the R5 ammo after blowing up the wall.
• There is no guard in the west area by the door from the entrance.
• There is no camera in the floor 50 laser room.
• There is no guard around the noisy floors on floor 50.
• There is no guard after the elevator on floor 98.
