Prince of Persia: The Two Thrones

- Missable - As you proceed through the story you'll see these portals surrounded by enemies. You can seal it in 2 ways: the stealth way and the brute force way. Every portal has guardians around it so you won't be able to close it till all guardians are dead. As stated above, you can deal with them with stealth kills or brute force: guardians positions are specially placed for you to be able to kill them all without starting a single fight. This will let you close the gate faster and with little effort. You can always soothe your blood thirst by fighting till the very last guardian but you'll have to fight more than what you see, because the main gate guardian will call for reinforcements, which will spawn one after another from the gate itself. Note: These portals can be skipped but it's really hard to do as you would need to totally ignore all the guards chasing you or even clean the portal and ignore it afterwards.

This trophy is related to Sand Might and Time Adept. As you close the gates you'll earn both Sand Tanks and Sand Powers. This trophy will unlock right after you sealed the last gate along with Sand Might.
