I just took that material from that game called SAS zombie assault 4. That game is from a website called ninjakiwi.com, if you want to play that game, go to ninjakiwi.com and have fun assaulting zombies.
Btw, that material was taken from those crates with weapons, armor and more. There are many types of crates, the lowest being the steel crate amd the highest
being "nanotonium" crates. To learn more about this game, i suppose you gotta play it at ninjakiwi.com.
