Assassin's Creed Mirage

During the “Branching Out” mission, you’ll be able to get one of 4 new tools (to add to your throwing knives):
 

• Blowdart
• Noisemaker
• Trap
• Smoke Bomb

If you choose the ‘Traps’ tool, you’ll be able to start working on this achievement pretty early on. It’s pretty straightforward: unlock the traps, throw the traps, trap 10 guards.

Now, there are a couple of ways to make this a touch easier - unless you’re literally just throwing traps at guards, which is a perfectly viable strategy:
 

• Throw a trap by your feet, or maybe a few, and then get the attention of a load of guards and drag them over. Bosh, the guards will trigger the trap
• Eagle Sense - The third skill you can unlock in the Predator skill tree allows you to see a guard’s path with Enkidu, your trusty feathered friend. Now you know where the guard is going to walk, why not throw a trap in its path

You only need to get 10, so you’ll breeze through this one, no doubt. And if you don’t decide on the trap out of the gate after the “Branching Out” mission, you can unlock more tools with skill points, by purchasing ‘Extra Tool Capacity’ (ranks 1-3) in the Trickster skill tree. You need to unlock them all and upgrade them to the max for Tools of the Trade (30G) anyway.
