@knanaq, you have to find a metal plate located on the second floor of the house, it’s in the same room where you can find health kit by breaking a small panel under monitors. After that, you bring it to the battery, ask a friend to sit down, and put that metal plate on top of his head. After that, you will be able to stand up on that metal plate and reach the battery.

Or just use prop jumping with that plate if solo. Another option to wait until crawler zombie spawns, that will allow you to jump on him, and perform another jump either to try reaching the battery, or jumping on the regular zombie’s head, which will ensure you a 100% grab chance of the battery.

Another option is to try throwing medkit or bandages at it, might work after some tries.

It’s easy.

Shame its not your map so you can't fix it, but the teleport keypad room is horrid. Code does not always match the one on PC and changes randomly each time it is entered, turning it into just Death Roulette. If anyone else wants to try this, be aware of this stupid keypad. Have only one person enter the code at a time and make sure everyone else is at the bottom, so they don't get killed en-mass if code is wrong.

horrible map

This map has many parkour parts.

great job nice
