Well iv got the pal version (wether this is relevent i dont no but)and if u shoot vamp he looks at u then snake shoots though most of the time iv taken head shots and he goes out on about 6 on hard and 1 on v.easey i think its just snake takes a ###### long time to take aim *if u notice the cyphers he shoots 1 and if it dunt go down in 1 shoot *he fires again at it after about 10 secs on hard he iz realy slow at taking aim for such n "Ultimate Soldier"
