Crysis Remastered

This is the second story-related achievement you will get. After unsuccessfully chasing the alien that took Jester, you will eventually find his body. After this, you will be tasked with rescuing a hostage, who is at a nearby village.

The village is a rather large area with plenty of KPA around, with manned turrets, as well as a minefield surrounding it. To avoid the minefield, take the bridge across. When you get to the building with the objective marker, you will come to a door where you can hear people talking (don't open it yet - you will get a prompt to open the door).

Before you open the door, I would suggest clearing out the village as much as you can first - more on that in a second. The hostage and a KPA soldier will be in the room, and after the enemy is taken down, you will talk to the hostage, who is one of Rosenthal's achaeologists. Psycho will enter room, and they will eventually leave. During this cutscene, the achievement will pop.

Once Psycho and the woman leave, you will be tasked with taking out two KPA tanks. There are several missile launchers in the near vicinity you can use (each tank will take at least two hits). This is where the suggestion to clear the village helps, so you don't have to deal with the tanks plus all the others soldiers at the same time.
