What was your last achievement/trophy?

Cap-ogee - Team Fortress 2.

Dark Boy in The Binding of Isaac ^__^

The City of Angels in L.A. Noire on Xbox Live, Bridge Building in Portal 2 on Steam.

200 beat chain in BIT.TRIP BEAT.

The Messiah in Dragon's Dogma, killed the Ur-dragon (offline) for the first time last night.

Gotta Break Em In -- Saints Row the Third, achieved by completing "The Ho Boat" mission.

Recently got Perfect Knight 2.0 or something like that for beating Arkham City, New Game Plus, all upgrades, all sidequests, all 440 (!) Riddler trophies, and getting 3 medals in all Riddler Challenge rooms. Yeah, that took a while.

Nice to see I'm not the only one who caught the BOI bug lately. Just unlocked ??? myself too =D

"Made It" (beat the game) and "Ironman" (beat the game without shortcuts) from Spelunky.

So this got bumped--

"Into Dripstone Cave" in Dragon's Dogma. Not much to it. You walk into the cave (via a well) and BLAMMO, achievement earned.

Silent Hill 3:

Where's Luna?

Unlock the "Princess Heart" costume.

I laughed out loud when I "activated" the costume.

"Completed Part III" in Max Payne 3. Not a very interesting achievement.

Having a Ball, from Dead Money.

I just got a trophy for loosing against Emizel in Disgaea 4........yay for participation awards.

Alan Wake:

Float Like A Butterfly (Dodge a hit)

Under a Thin Layer of Skin (Kill the Park Ranger)

So far I'm liking Alan Wake for the story, the combat doesn't seem like much fun.

Vampire Mastered, Skyrim expansion.

Got My S rank back.

Apparently... (I think that means winning the game as Gustavus Adolphus)

Halo Reach: License to Kill

Anniversary: Ran over 5 people with a vehicle in a matchmade game.

Grand theft auto: the lost and the damned / the 1%. I just got this on PC thanks to one very kind duder giving it away and although im starting with the main game i booted this up last night to make sure it runs ok and ended up getting this achievement.

Rainbow Moon

Don't Worry, Be Happy!

I got the one for completing Deus Ex on the hardest difficulty. Which was pretty damn easy given the stealth approach I adopted not to mention that I scoured every single area for them Praxis points.

That one achievement without setting off the alarms is pretty finicky though, I'm not sure what I'm doing wrong since I don't remember failing any hacks or setting off any alarms.

A friend and I are racing to finish S-Rank Secret Of The Magic Crystals. I seem to be winning, as I just finished all of the first tier races and quests. (Doing both of those things awards achievements, can't remember which I did last though.)

KoA: Reckoning

Some of This, Some of That

Unlocked a two-class hybrid destiny.

Explodonator in Plants Vs. Zombies for Windows Phone 7.

Is this JUST for Xbro or PS3?

Because according to GB, my last achieve was: Bloodthirsty Berserker on my little Dwarven Shaman.

オシャレ伝道師 in Persona 4: The Golden. Beats me.

Petty Miner - Space Pirates and Zombies. Awesome game btw. BUY IT!

KoA: Reckoning

Jailbreak

You broke out of jail.
