So, I’ve since tweaked my earlier achievement suggestions and added some new ones. I’d like to think these cover all areas, and are NOT grindy as hell (which is what the achievement community clearly does not want for this last batch). And yeah, I have some challenging, but REALISTIC, suggestions:
Achievement Requirements: Complete a 50 wave variant of Horde on Insane difficulty without failing a wave challenge. Note that failing the wave itself (by having all players die) would void this achievement for the match.
Achievement Name: Challenge… Accepted?
Achievement Description: Complete a 50 wave variant of Horde on Insane difficulty without failing a wave challenge.
Achievement Requirements: Perform one of each of the unique executions on a downed enemy in public versus matches or in Horde. This includes - Combat knife CQC (from any direction), Beatdown, Overkill, Dropshot, Enforcer, Markza, Lancer, Retro Lancer, Longshot, Boltok, EMBAR, Gnasher, Salvo, Tri-Shot, Buzzkill.
Achievement Name: Kick 'Em Harder When They’re Down
Achievement Description: Perform all 15 unique executions on a downed enemy (Public Versus or Horde only)
Achievement Requirements: Reach Wings 1 (Re-up 11). This should be an easy unlock and a welcome reward for most dedicated players, who are likely already past Wings 1 : )
Achievement Name: Wings!
Achievement Description: Re-up for the 11th time and earn your wings!
Achievement Requirements: Complete the Prologue in Co-op, on Inconceivable difficulty, with Ironman turned on. Also, reloading checkpoints should be disabled, to ensure it’s done in one sitting.
Achievement Name: Brothers in Arms
Achievement Description: Complete the Prologue on Ironman in Co-op on Inconceivable difficulty, without reloading checkpoints.
Achievement Requirements: Freeze an enemy using the Despicable You easter egg gun (found in the prologue), then shatter him.
Achievement Name: You’re Despicable! (secret)
Achievement Description: Freeze an enemy with a special weapon in the campaign, then break him to pieces.
Achievement Requirements: Kill an enemy with the Despicable You, Dom’s Toms, Memento Mori and Raging Buccaneer weapons in the same campaign chapter. This will require players to at the very least have the Despicable You, Dom’s Toms, and Memento Mori equipped upon entering Act 3, Chapter 4.
Achievement Name: Sunday Easter Sunday
Achievement Description: Kill an enemy with each of the four ‘special’ weapons in the same campaign chapter.
Achievement Requirements: Perform a headshot kill while holding a meatshield 25 times in public matches (note that this can only be done with either the snub or boltok pistol)
Achievement Name: Pistol Mastery
Achievement Description: Get 25 headshots while holding a meatshield (Public Versus only)
Achievement Requirements: Earn a kill with a grenade tag, planted grenade and thrown grenade in the same Public Versus match 5 times.
Achievement Name: Grenade Mastery
Achievement Description: Get a kill with a grenade tag, planted grenade and thrown grenade in one match 5 times (Public Versus only)
Achievement Requirements: Kill [any member who suggested this type of viral achievement], or anyone who has this achievement, in a public versus match. Note that the Achievement Description would list all gamertags of members who have suggested this (not just myself), provided the list is not too exhaustive (I haven’t gone through the entire thread, but I can almost guarantee that other members have suggested this kind of viral achievement)
Achievement Name: Lambency 2.0
Achievement Description: Kill Reaper08R, or someone who already has Lambency 2.0, in a Public Versus match.
Achievement Requirements: Do either of the following as a team of 5 different Zombie characters: Win a competitive match, or complete a boss wave on Insane difficulty. Note that the 5 characters MUST be different (i.e. no 2 teammates can be using same zombie character skin)
Achievement Name: Like a CORPSE
Achievement Description: Win a Competitive Versus match, or complete a Boss Wave on Insane as a team of 5 unique Zombie characters.
