How to unlock the David and Goliath achievement in Prince of Persia: The Forgotten Sands - Definitive Guide
Attack the titan's legs until it gets down to half health - it will kneel down. Get behind it and jump, which will start the aerial slash animation - wait until your sword flashes yellow before hitting X to execute the titan.
At this point you can reload your last checkpoint if you want to get this achievement done right away, or you can simply keep playing as there are more than 5 titans through the story.
If you played through the story mode already, there's a titan in the 8th round of enemy tides, so you can play that repeatedly to get the kills.
Here's a video I found of a titan being killed by aerial slash
Do this 5 times and you'll get the achievement. There are more than 5 titans to try it on so don't worry about missing one or two because you can still do this in Trail mode.
Your character should be quite a hard dude by now, and after the cut scene, you get a Titan and some skeletons. Activate stone armour and just power attack his legs (hold X), until he kneels down. Then jump up on him (A) triggering a cutscene, and hit X when the Prince's sword flashes white light.
After this, just let the skeletons kill you, don't rewind time, and the checkpoint start is where the Titan spawns. As a result, if you want to, you can knock this out in 5 minutes.
These are first encountered in the ‘Ruins Of Rekem’ section. The titans come out of the ground and wield a club/sword like weapon in one hand. To be able to perform an aerial slash on the titan you firstly need to get its life down to less than halfway, just do this by attacking it in any way you choose. When you see the titan kneel down on one knee you know it is time to do the aerial slash.
To initiate the move simply press when next to the titan to jump up onto it, then press . The prince will then jump up ready to strike, when you see his sword flash with a bright shine press again & this will finish the titan off.
I believe I counted 7 titans through the normal game play so you can miss 2 and still get the trophy. However, if you missed more than 2, don’t worry because you can get another chance at killing them in the challenge mode that is located in the main menu.
