This is best done while playing as the archer and can be done with any bow found in the game. While any character can use the rope bow for kills it is a VERY slow way to get this achievement.

This is best done while playing as the warrior and can be done with any sword found in the game. All non-warrior classes can get his with a sword they forge in the game.

You will come across enough cyclops in the story to get this, just make sure you kill them rather than sneak by them. The cyclops are normally found in areas that have traps you can activate to do extra damage to them. Its eye is also more vulnerable, so attack it if you can. The cyclops you meet at the beginning of the story does not count toward this achievement.

This is part of the storyline, so you won't miss it. Just kill all the enemies.

This can only be done as the asassin. Once you learn this skill, press and hold to sneak up behind an ememy. When you get close enough to them you will see your hand reach out, at this point pull to stab them in the back.

This is best done while playing as the Mage and can be done with any spell that does damage. Non-mage characters can use scrolls (that do damage) that are found throughout the game to work toward this achievement, just be sure that the enemies are dead and that you used only scrolls (magic) to kill them.

Simply kill a combined total of 50 spiders, undead or ghouls. If you kill everything you encounter you will get this well before you finish the game. Be sure that you actually kill the undead with the finishing move or they will not count toward this achievement. To perform the finishing move, hold until your weapon flashes, release to ‘finish’ the undead.

A nice guide to all the relics (also secret areas and equipment) can be found here.
The relics must all be recovered in one play-through.

Meeting Aratrok is story related, he is the Orc leader you encounter while searching for the Skull of Shadows. Before you fight he will talk to you about an honorable fight (no magic). Simply kill him without using any magic. Magical weapons are not a problem, just avoid using spells or scrolls.

As you progress through the game you will learn how to change into demoniac form. Once you have this ablity, kill 10 enemies while demoniac. These kills accumulate and can be done as you progress through to the end of the game.

Difficult mode is very do-able. Instead of the usual toe-to-toe fighting you'll need to move more, block more and use more health potions (be sure to place your health potions in the on-screen quick select menu). Save often to avoid lengthy do-over's.

When you encounter Ishtvan, you will see the two chains supporting him. You'll need to back track, following the chains, to find the areas where you'll disconnect them.

For the first chain, go back to the room you came from, you'll see the chain coming out of the wall into a stone. Climb up onto the ledge and disconnect it (There is also a relic here).
For the second chain, face Ishtvan. Behind you and to your right is a broken staircase. Climb the chain that is hanging here, and continue up to the suspended area. The second chain is over the archway to your left. If you have trouble, just look down at Ishtvan and follow where the chain goes.

This is storyline related. While you are hunting down Arantir in chapter 8, you will have the option to rescue Leanna. Choose to save her and follow the signs to the Spiders Lair. On normal difficulty, one good adrenaline power strike will take care of the spider guarding her. Saving Leanna also gives the story option of redemption later on.

This is story related. Go up into the tower to your right as you're coming up the hill, you will find a ballista mounted against a wall. Wait for the PaoKai to hover and give it a few shots. 2-6 shots should kill it, depending on your difficulty setting.

Complete the first section of the game to get this achievement.

This is story related. Kill the big spider by luring it in-between the pillars and thowing the switches to burn it. The switches take a little time to reset, so keep a distance from the spider until you can repeat the process. Once the spider is dead, go behind the wall in the main room to recover the Skull of Shadows.

Complete the game on any difficulty level.

This is story related. Kill all the necromancers, take control of the boat and the achievement is yours. Be sure to go below deck and do a thorough sweep of all areas if you're having trouble.

This is story related. Once you pick up the last gem in the temple you'll get the achievement.

This is story related. Once you reach the Necropolis you'll get the achievement.

In the altar room you will see an open door with a raised gate above it, you'll need to lure the dragon into that doorway to kill it. The dragon is attaking Leanna, you'll need to draw it's attention to you. Walk in between Leanna and the dragon and hit it with your sword when it's low, with a spell or with an arrow, anything to make it focus it's attacks on you. When that's done move into the open doorway and wait for the dragon to put it's head in the opening. Pull the lever to close the gate on its head to kill it.

As the Mage cast freeze on the ground in front of approaching enemies and make them slip on the ice patch. This can be done with scrolls.

As you kill enemies your adrenaline bar will fill. When it is full press [img]http://www.xbox360achievements.org/images/misc/x.png[/img] to activate adrenaline mode. Be sure to be close to an enemy as adrenaline runs out very quickly, use a power strike to kill them.

If you play as the assassin you will be able to detect some of these areas as they will glow blue, but many secret areas are, well, secret and not easy to find. A list of secret places can be found here. You only need to find 42 of them.

During the course of the game you will encounter forges where you can make swords. Different metals can be found during the game, but most forges will have everything you need. A book in the forge tells you the process required to make a sword or you can use this video (taken form the PC version, so it looks slightly different)

Activate adrenaline when you are close to a group on enemies. If they are standing close enough you will have time to kill two with an area/spin attack.

The is best done as an assassin, since you have the sneak ablilty. Hold [img]http://www.xbox360achievements.org/images/misc/rb.png[/img] to sneak up behind an enemy that is standing near an edge. When in range kick them by pulling both [img]http://www.xbox360achievements.org/images/misc/lt.png[/img] and [img]http://www.xbox360achievements.org/images/misc/rt.png[/img] at the same time. You must do this five times without being seem by them.

Kill a combined total of 50 enemies without using a weapon or magic. Activating traps, kicking them off edges, onto spikes or into fire (this is slow) will work. Throwing boxes and crates at them also works but you'll have to hit them 2 or 3 times to kill them this way.

Self-explanatory. The hardest part here is finding people playing online. Organize a group of friends to help you with this. Must be ranked.

This can be tough without friends to help. Organize a group of friends to help with this, just watch your time. Must be ranked.

Self-explanatory. Finding seven other people to help will require some organization since very few people still play this game online.

Crusades can be played in Player Matches. You'll need to organize atleast 7 other people to help with this. Crusades take longer than other games, because you have to fight each map for territory. That means you'll have to play through 3-4 maps before the game ends. Win 10 crusades as humans.
