Conan

Its possible to do earlier in the game if you unlock Cimmerian Cyclone. Otherwise on the last level there's a point where you have to push a pillar over to create a bridge, it begins to crumble as you cross it. When you get across, you'll fight a bunch Oilmen. Use the 'Cimmerian Cyclone' Dual-Wield Combat Ability x, x, x, +(hold). You can also get "Chain of Fools" using this technique.

To earn this achievement, your combo counter must reach one-hundred hits or kills (doesn't matter which, actually).

I actually earned this in the beginning of the last act, Dark Prison. There will be enough oilmen and demons for you to slay at the start of the stage. You just need to wake them all up and lure them into an area big enough to move around with, such as the right side of the beginning. You'll know what area I speak of when you see a treasure chest at the left side of that open area, the very first treasure chest of Dark Prison.

Before you earn this achievement, you must do the following first.

-Beat the game on Hard and King, earn all the cheats.
-Make sure you have them all on.
-Get to the last area.

If you don't have the Master All Moves cheat on, then you have to unlock the Cimmerian Cyclone and have two weapons, one in each hand, to perform the move. Once you have unlocked the move and have one weapon in each happen, you must press X, X, X, then press and hold down X to execute the Cimmerian Cyclone. As you are holding down the X button, make sure to move Conan around as he is spinning with his chosen weapons.

Once you did all that, start up the Dark Prison level and wake up everybody. Once all the demons and oilmen are alerted to your presence, lure them to the area I described them above, the one on the right side. You should then input the button command I describe above and begin the killing process, hitting as many as you can. Make sure that the combo DOES NOT BREAK - otherwise, you will have missed out on your chance and you'll have to reload your saved game to try again.

It was very easy to score one-hundred hits/kills with the Cimmerian Cyclone and it took me my first try to do so! However, for some of you, it may be very different and will take several tries until you got it down. There's a video in another solution that shows exactly what needs to be done, but I hope my solution helps you out to the best of my ability!

Have fun and good luck!

On the Monster attack level (giant squid) there are three oilmen that respawn infinitly. Use the body slam (b+b) with correct timing and you can get a 100 chain easily. The 325 one cannot be done with this method.

I found a really easy way to get this.

If you have already completed the game on Hard mode and got the infinite sheild armour cheat, activate that first.

This means you can cast "Stone Prison" a heap of times on a group of enemies and it counts as a combo "hit".

I found to do this easily, on the Devil Island level if you turn the crossbow to aim at the box on the end of the pier, and stand behind it, the enemies don't go around the end of the crossbow and get stuck behind the trigger end. You can then cast stone prison on them as many times as you like. This can also be used to easily get the "Chain of Fools" achievement

I learned this solution from reading Gannicus Juteu's solution on the 325 achievement and ended up getting 220 or so combo pretty easily. I will try again later and I can probably get the 325.

On the fourth level (the sand level), you fight the sand dragon. There is a short cutscene where the dragon eats somebody. Take its health all the way down using dual wield and X attacks. When its health gets to zero, the dragon's head flops over to the right and you can keep attacking it, maintaining your combo. Be sure not to hit Y. After a few seconds the head goes back to the middle, quickly hit it several times and the head flops back over. Just keep repeating this process being careful not to let the dragon attack or your combo lapse.
