How about each set i.e. all the Lock down Achievements, follow a theme? Like, Locking things up/down?

If so, I can suggest some things. (Format - [Achievement name]: [Description]). '???' means unknown.

Lockdown (Theme: Locking up/down, combat)

• Lock & Key: Win your first Lockdown Match
• Bronze Lock: Win 10 Lockdown Matches
• Silver Lock: Win 25 Lockdown Matches
• Gold Lock: Win 50 Lockdown matches
• ???: Play one match on each battleground

{We should attempt to exclude any achievements which require people to be a specific class/do specific things, since it would force people into doing them. Just think about? An Achievement saying that you have to give someone the death mark x times would lead to people being the Recon even if they didn't want to be.)

Blast Network (Theme: Blowing up (things), Networking?, Bomberman)

• Brings back Memories, doesn't it?: Play a game of Blast Network
• Amateur Bomber: Play 10 Games of Blast Network
• Average Bomber: Play 25 Games of Blast Network
• Adept Bomber: Play 50 Games of Blast Network
• Power UP!: Collect over 100 power-ups in total

{These appear to be the extent for Achievements for Blast Network: Playing Games; Winning Games; High-Scores; Power-Ups; and kills. Other than that, I have no idea what can be turned into an achievement.}

Shadow Lair (Theme: Any)

• Sanctuary: Reach the Sanctuary
• Poisonous Darkness: Defeat the Rabid Snarbolaxes in their Dark Woods
• Frosty Reception: Defeat the Ice Queen in her Icy Palace
• Dangerous Duo Destroyers: Defeat the Red Roarmulus Twins in their unsafe abode
• ???: Face off against Darkfire Vanaduke in his firey kingdom
• Glutton for Punishment: Visit the Shadow Lairs more times than necessary

Missions (Theme: Militairy progression i.e. Ranks, Any)

• Ground-pounder: Complete X missions
• For the Memories: Redo any completed Mission

P.S. I think that if the Achievements are going to be expanded this much, it's time to put in a way to sort through them all.
My best idea is adding a drop-down tab under the Achievement Tab in the Character Menu. The tab would have categories like: Exploration, Boss, Alchemy, Collection, Minerals, Aid, Survival, PvP and All. And those that fall into that category would show up (Only one category at a time).
I guess the code-side would be handled by the drop-down Tab asking whether the Achievements have the selected Tag, then showing them if they did.

Complete a gauntlet final room with all members dead, save for completer and without dying.

BUT!>... aren't achievs useless?

And I don't mean I don't want new achievments, but you get nothing for completing them except a picture in your profile thingie which OTHER PEOPLE CAN'T EVEN SEE OR ADMIRE!
If they would make sure you could see other people's achievs i'd actually try doing them, like with prestige atm.

But for lockdown you could use something like:

• "Lock and Load": Win a Lockdown match
• "Bring 'em down": Win 50 Lockdown matches
• "Capture Guru": Capture 25 HUDs
• "King of the Hill": Capture 50 HUDs
• "Guerilla Tactics": Defeat 50 opponents in Lockdown
• "Art of War": Defeat 100 opponents in Lockdown
• "The Turtle's shell": Defend 25 HUDs
• "Bastion's Wall": Defend 50 HUDs

Also, why not class specific achievemnts in LD? Most of the time i see teams of strikers with 1 guard VS a team of strikers... (true story T_T)

Exactly!

But we focus not going towards any achievements which focus on doing anything too specific, or something which relies on luck i.e. soul jellies and Love Puppies.

@Hyperanthony: Those should probably get the name 'Cartographer' or something.

Otherwise: +1

I like it, when you have achievements that have to be completed in the arcade, it will immediatly solve the dead-unused-arcade problem. Perhaps get some rewards for some achievements, like accesoiries or even emotes.

Love this idea, as we do need more achievements. I think we should have class specific missions in lockdown, because what's the harm of it?

im not against it. if i wasn't able to see my achievements, i would be annoyed because of the research i would have to do to find out which achievements is out there and how to get em. i do agree with having luck achievements though like getting 3 uvs on a crafted weapon. that would be awsome.
