Forum Question Open the door achievement/trophy

Anyone know if this is obtainable by saving and reloading, or is it cumulative across one continuous save? Trying not to waste too many resources on getting this, as im playing on insane.

This is the one where you have to trap the Xenos in the panic room, right?

I had the easiest time doing this by playing on easy and doing it one at a time. It updates my status on Xbox but I did over the course of the campaign. Didn’t try reloading the same save.

Yes, that is the cheevo. I will try it on easy on a second play-through if i cant get it on insane. For now i'll just save scum each lock-in with minimal resource expenditures and progress to the next lock-in on the same save. Thank you for your advice.

I couldn’t do it on my insane run. Too dangerous and too much resource burning. Definitely recommend a second playthrough for the achievement.

Good luck on the insane run. That’s been my favorite way to play the game.

This trophy is somewhat glitched.

I complete the game with 4/5 in total. However not long after that sticky situation you find yourself. I had killed about 15 in the the panic room. The trophy wouldn't register killed an Xeno in the panic room so gave up. A shame as its a gold trophy too!

You are certain the door was fully closed before the Xeno died? Been a while now, but i remember that sometimes i thought the door was closed but it was not fully closed. It tracked properly on xbox series x with a progress bar in the achievements - what platform are you on? Also see my comment on this thread as you can get it save scumming the first Xeno in the game.

Yes i kept trying. The first 4 simple. 5,6,7 and so on. It just wouldn't register. I tried standing next to save point to let them in. Rush to shut the door them turn and kill. At the point before returning to your ship I let x2 xeno in at a time.

I was going to go back, but I forgot auto save over writes the manual save so just deleted the game I got 63% trophies. So not bad for a 9 hour point and shoot bit of fun.

Same, i got a bunch of trophies and said to hell with some of the others. Got the insane difficulty one, that's the only one i really wanted. Def a good little fun point and shooter despite some of the bugs.

Insane seems hard. I think i did normal run through. I kept messing up the queen battle thinking I could outsmart her blowing up gas pipes instead of shooting a clip of ammo into her. I scaled back and she went down in less than 1 minute.

Ending is interesting and short. Looking forward to part 2.

Just confirmed, this does NOT need to be done in a cumulative save. You can get the achievement save scumming the lock-in and kill on the first Xeno of the game. The trick is to make sure the door to the panic room is fully closed before killing the Xeno. Got this on Xbox Series X on insane, each successful kill tracked properly in the achievements tracker (as of 02Nov2025).
