6. Batman: Arkham Asylum - Freeflow Combo 40
Complete a combo of 40 moves. One of the best things about the much celebrated Arkham Asylum was its combat system. Not a particularly difficult achievement to unlock with a couple of attempts, this one just allowed the player to simultaneously indulge in what was an incredibly well-designed element of the game whilst feeling like an absolute badass.
7. Brutal Legend - Conqueror
Win 50 multiplayer matches. Another depressing achievement for two reasons. Firstly, the third-person, real-time strategy hybrid was a great idea executed in a mediocre fashion and playing it through fifty times is a sad reminder of how close Tim Schaeffer and his team came to brilliance. Secondly and this is a common problem amongst games which sell poorly - nobody plays the multiplayer, therefore making it almost impossible to get this achievement unless you find a friend in a similar position who is willing to play a hundred games with you. Which is very unlikely.
8. Assassin's Creed - Conversationalist
Go through every dialog with Lucy. Yet another sneaky twenty gamer points that is infuriating not because it is particularly difficult but because its the only one in the game that is completely missable, therefore requiring you to play through the game again if you dont take advantage of every line of dialogue with Lucy. Ive nothing against missable achievements, its just when theyre so exasperatingly surreptitious it kind of feels like the gaming equivalent of a wedgie.
9. Guitar Hero 3 - The Inhuman Achievement
Complete Through the Fire and the Flames on Expert. Despite its rarity, everyone knows someone who boasts this achievement. Rhythm games have come a long way, but Dragonforces first entry into the Guitar Hero catalogue is scorchingly tough and requires hours upon hours of practice to even be able to finish, let alone on expert difficulty. Given the relative popularity of the franchise, its also probably one of the most famous achievements in this list.
10. Final Fantasy XIII - Treasure Hunter
Held every weapon and accessory Some of the most depressing points on this list, Treasure Hunter is another completionist achievement which not only neglects to provide a decent explanation of your goal but also strips away a lot of the fun of playing the game. In order to get this, the player must basically never sell a single weapon or accessory they pick up and make sure they upgrade one of everything they acquire, which in turn requires a large amount of components. The sheer amount of time and money involved in getting this achievement is phenomenal, especially for a game which, similar to Dragon Age 2, suffers from being restrictively linear in a series which traditionally encourages open world freedom.
