Tips for Dead Air - Crane solo survival?

[Ref]

For the other survival maps, I'm able to consistently survive well with them. Crane is the only survival map that is hard to consistently survive on, and so i was wondering if anyone had any tips. Thank you for anyone who replies!

Only reach the other building with two open windows then go for a ak and some gascans there is a good place in that building near the ladder just climb until the bots follow you up there then go down and camp the crane you will se commons and specials climb that crane or building below your feet so be carefull when a tank spawns kill him and run with your bots for ammo and repeat previus process in 5:20 two tanks will appear so use your molotov or your gascans to burn them you only need to survive until 9:10 after that the place start to go quiet this only requires patience and luck so good luck this also works with people
