Gangster king

You use your M16 to shoot the driver of the van the van slides off of the road into the forest and then it crashes into a bunch of trees and tips over one of the dying men says "What the fuck was that man!" Before he loses grip and falls out of the van. As your van keeps rolling into the forest you start to lose grip as your body is very damaged you grab the light that is on top of the van but that quickly break's but with it breaking you find a chain... Maybe this chain can keep you from dying but you need to act fast as you are very damaged.

Time is running out so what will you do???
