    This achievement can be unlocked pretty early in the game but is missable.

    Right after the scene with Zsasz and the guard you will talk to another guard who tells you about some trapped people in a room filled with gas. As soon as you made your way around to the room (through a vent shaft again) you' ll need to save 3 people in this room. 2 guards and 1 goon.
    The first guard you need to save is the guard who is hanging from the same platform you are standing on when you entered the room.
    The second guard is hanging from a platform directly above you. You need to press cn_RB to get yourself up there.
    The third person would be the goon. From the position of the second guard you need to glide over to the position of the goon which is a lillte bit lower than the position of the second guard. As soon as you have saved all 3 people the achievement will unlock.

    If one of these guys dies you need to dashboard and start another game to get Arkham shut-down and hope for an earlier checkpoint to kick in.

    If you need further help, please refer to the video below.

    DrewskiMcGeeI cannot get this to unlock. Followed exactly what was in the video and other descriptions of the getting the achievement. I've tried reloading from checkpoint multiple times, quitting out of the game, and restarting the console. All to no avail. Luckily, this is early in the game, so I'll just try a new save file.

    Update: Randomly unlocked at the start of a new save file. Oh well.

    This achievement is unlocked upon rescuing the two guards and one henchman from the Joker toxin in the Decontamination room.

    NOTE: MISSABLE

    After leaving the vent from the Patient Pacification Chamber at the beginning of the game, you will follow a guard into a room. The Decontamination room on the other side of the glass will fill up with Joker toxin, and you will have to help them. Afterward, look up and grapple up, then enter a vent into the Decontamination room. The first guard will be located on the right as soon as you enter, press cn_A to drag him up. The second guard is located after a jump when a ladder explodes. Grapple up and drag him up. The final person is a henchman which is located on a lower platform that you have to glide to. At the far end of the platform, you will find him and drag him up again.
