How to unlock the Bad Meal achievement in METAL GEAR SURVIVE - Definitive Guide

External image

After beating the main story you can randomly find a red circle on the Dite map that says "powerful enemy detected". If you go there you'll find an enemy called Big Mouth. One of his attacks has him try to bite you. If that attack hits an explosive barrel gadget he'll eat it, take damage, and you'll get this achievement.

Some tips for fighting him. If you are using the scout subclass the stealth ability and fox step ability will let you easily clear all the basic wanderers in the arena and place some barrels. A purple shotgun with about 70 rounds should be enough to kill him. His first phase is pretty easy if you don't have any additional enemies, just hide behind a pillar in the arena and when he's not shooting you can pop out and shoot him a bunch. After he staggers from the shotgun he'll usually try a bite attack so you can place a barrel at this time if one isn't nearby. His second phase is a bit harder since his attack is a bit more instant but you can use the cloak to get in free hits and then hide while waiting for it to recharge.

Explosive Barrel can be found North of teleporter 9 on the main map. Following the bounds of the map on the east side it should be the second container north of that teleporter on the attached map.

No longer missable since boss can spawn in daily/weekly missions.

Addendum: As of most recent patch (4/3/2018) boss side missions now reappear in single player and can appear in new areas. Just refought bigmouth on FOB map half way between T6 and T7.

It would be great if you enhance your guide with the edit option and include a description of the location of the explosive Barrel that you suggest we use. Thank you in advance.

I believe this is missable as no one has been able to get the boss the spawn again after killing him

Anyone have a video of the drum achievement? I have placed countless drums in front of him and he just ignores.

What's the purpose of the current picture for this guide? Are we supposed to get something out of it? Is it leading us somewhere?

Someone asked where the barrel is. That map shows containers and my write up says which one specifically.

Another tidbit that might help some people out, if you do have the Scout cloaking ability unlocked, or are just fast enough, get as close as you can to Big Mouth, place the explosive drum, and then throw a decoy right next to the drum. Doing so should have Big Mouth eat the drum first try.

This can always be done in private Co-op if missed the first time.

I'm fighting the big mouth in the co-op missions and I cannot get him to eat a drum. Probably because he's higher level. He keeps shooting at me or charging. But your Technique should work and I'll get it eventually. Thanks for the suggestion.

To fight BIG MOUTH again, go to:

-CO-OP Missions.
-Tab over to RESCUE MISSION.
-Choose Rescue Mission: [Forsaken Ruins].

On the mini map, the large red diamond is Big Mouth.

There are only two boss creatures and only one of them has a mouth so that's the easy part. When you fight Bigmouth for Suppression you will notice he has a number of attacks. One of them being the Bite, where he takes a leap back and then rushes forward with open mouth in an attempt to munch you. Make sure you craft Metal drums before you go and meet Bigmouth. Stay close to him to trigger his Bite attack, plant a Metal drum in his path and hope he munches it. This sounds easy but might take a few tries so make sure you max out on the drums you take with you.

To be sure you get the idea, here's a video:

You need to feed the barrel to one of the “endgame” bosses. The one that looks like a Tyrannosaurus. From time to time he makes an attack where he runs with his mouth open and his head down. You need to put a barrel in his way.
