Xenolith666 Posted February 11, 2011 Share Posted February 11, 2011 CoD 4: Mile High Club FF13: Treasure Hunter Definitely the most time consuming in my gaming career. Link to comment Share on other sites More sharing options...
Ravenhood Posted February 11, 2011 Share Posted February 11, 2011 Without a doubt, the longest one for me has been from WarTech: Senko no Ronde. The achievement? It's called "100 Hours". Can you guess what you have to do? XS Play the bloody game for 100 hours... hard to do when the single player stuff lasts, at most, 5 - 10, and the multiplayer stuff about 40. My next longest achievement will be from Beautiful Katamari, which also has a 100 Hours achievement... v.v Link to comment Share on other sites More sharing options...
caustic christ Posted February 12, 2011 Share Posted February 12, 2011 Madden 08, throw 20 consecutive passes (no drops). Link to comment Share on other sites More sharing options...
TuMaBlAcK Posted February 13, 2011 Share Posted February 13, 2011 As of right now my longest would have to be All missions Complete in DW:Gundam 2 with total game time at 122Hours when I finnaly got it. But I think once I get Solid Gold in FM3 or I start playing ToV it'll top that. Link to comment Share on other sites More sharing options...
P0WERHalf Posted February 13, 2011 Share Posted February 13, 2011 The achievement that took the longest in one sitting was ( Mile High Club) from Cod4. It was definetly the hardest and most frustrating achievement that I've unlocked. The achievement that took the longest was probably the one from Skate., where you needed alot of overall xp in multiplayer. i think it was 200k xp.

Taccer Posted February 14, 2011 Share Posted February 14, 2011 As in real time and effort? Halo Wars' Running the Show. However, it took me a rediculously long time to get the right strategy to get Black Pearl Pooh-Bah on Hexic. Link to comment Share on other sites More sharing options...

Hitchman Posted February 15, 2011 Share Posted February 15, 2011 Seriously in Gears of War. I had about 6000 kills before i started the boosting and it took me 12,000 total kills. Maybe 200-250 hours total. Link to comment Share on other sites More sharing options...
Aki2403 Posted February 15, 2011 Share Posted February 15, 2011 (edited) That I have unlocked, Solid Gold In Forza3. In a single sitting, Invincible in Serious Sam TFE. That I've not unlocked yet, but have been "working on" for far longer, 1,000,000 Online Credits in Forza2.

ginge88isfun Posted April 9, 2013 Share Posted April 9, 2013 This probably isn't the longest achievement, but for one sitting: http://www.xbox360achievements.org/images/achievements/1527/s6.jpgMan of 1004 Holds 100 http://www.xbox360achievements.org/images/site/gp-g.png: Perform a total of 1004 signature and finishing moves in any mode of play (offline) Doing this the quickest way known at the time I did it, still took an 1h 45m of non-stop signature/finishing moves THIS!!! I would also add, Zombie Genocidist on Left 4 Dead, took me weeks to get that one. Link to comment Share on other sites More sharing options...
FatalDeathSG45 Posted April 9, 2013 Share Posted April 9, 2013 Both of these achievements from Doom and Doom II, respectively. It took a long time to do each one, but I finally did them (Got the Doom II one yesterday! ) Doom: http://www.xbox360achievements.org/images/achievements/30/0Tc8P2Nh.jpg RAMPAGE (35 ) Complete all levels on Ultra-Violence Doom II: http://www.xbox360achievements.org/images/achievements/1180/-sJqrQ==.jpg Superior Firepower (25 ) Complete all levels on 'Ultra-Violence' or higher in Single player Link to comment Share on other sites More sharing options...

Deadsea 1993 Posted April 10, 2013 Share Posted April 10, 2013 (edited) Zombie genocidest in Left 4 Dead, took me months and months playing everyday doing legit to get. Second runner up would be What are you trying to prove in L4D 1 also did legit. That was my 2nd longest one Same with Genocidest took me months to get found a group of randoms that were actually good enough, helped me out with the other 3 campaighns i needed in one sitting and I got that achivement. Offline the team AI is dumb as fuck they got incapped within 5 minutes everytime. Thats why i couldnt do it nor L4D2 offline. I will get back to L4D2 for the ''What are you still trying to prove ?'' achivement but that game is no were near as good as the first. It got old fast.
