IMPORTANT NOTE: I forgot to add, this only works in the Free for All game type.
3:08 - Skip the tutorial if you just want to see the Easter Egg.
This is a pretty elaborate Easter Egg where you get to fight an NPC Epic Reaper on the Library map in multiplayer versus in Gears of War: Judgement.
1. Get into a public or private FFA match. It works with even just 1 bot.
2. Find the secret bookcase near the Fountain area. You need two Frag Grenades to toss into the area above. If youre doing it alone, pick up an extra from ammo boxes, or change the weapon pickups to Frag Grenades.
3. A painting will fall down, along with a piece of paper. The goal now is to find all 8 paintings scattered around the map, and shoot each piece of paper next to them to light up the COG symbol on the wall. Note that only the Snub Pistol works when shooting them.
4. Once youve found and shot them all, return to the secret bookcase area. The COG symbol should be completely lit. Shoot the painting with your Snub to start the fight. If you die, you can return to the area and shoot the painting to try again.
Note that this does not unlock the medal or weapon skin from killing a player controller Epic Reaper.
