The Texas Chain Saw Massacre

This achievement may sound easy but it really isn't. It's hard to build a guide for this as the matches can vary a lot and what will work in one match, won't work for another.

It will be best to get a good idea of the game and be flexible with how you plan your escape for this achievement.

You count as the last victim by any means necessary. That can be the other 3 escape before you, they are killed while you're not or a combination of the two. All that matters is after the third victim has escaped/died you survive for three minutes and then escape.

The difficulty comes with the escape, if the other three escape before you then the family will more than likely scout and block the exits they have fled from - reducing your options in getting out. Though this can provide a prime opportunity to try and escape from one of the other exits.

My best advice is to play as Sonny as his skill that allows you to see "noises" made by the family, in a set radius. This can help you decide which is the best exit to flee from and to note where the family is keeping scout of.

I will list some tips that may give you a bit of an edge in getting this.

1: Shut all doors and gates behind you. This might seem silly but it can throw off the family sometimes. They may avoid going into a certain area if they see a gate or door is shut as they'll assume that no victim is in there.
2: Try and aim to escape from one of the back exits (using the lockpick) IMO escaping from the basement (fuse exit) and the front of the house (main exit?) will be a lot harder than the other exits.
3: TAKE THINGS SLOW! I'm noticing a lot of players are rushing in the game and getting caught quite quickly. This game for victims works a lot better that use a stealthy approach.
4: If you get the chance, stab gramps! Stabbing him will knock him out for a moment or two but will also weaken him, this can give you a huge advantage later on in the game as once he reaches stage 4 you can't hide. To knock him out you will need a bone knife, which you can collect from the bone piles that you'll find mainly in the basement. Once you've stabbed him you'll lose your knife.
5: Once a gate has been unlocked the family can block/lock it again. Depending on the gate will depend on how they will do this, if the gate is electrified, they can set the electricity on again. So it may not be a good idea to unlock a exit and then wait 3 mins.

Overall, take things slow, locate a safe exit, wait till you're the last one left, wait three minutes and then start your escape.
