Resident evil 5's Pc version of Vigo, play.

Give Chris the bazooka. Don't turn off all the lights before you come up. There is also a rocket launcher on the first floor. Let Sheva take it (if you take it yourself, he will follow you and it will be very troublesome). If Vaske is still chasing you, keep your distance from him. When you see him grab the bazooka and give him another bazooka, he will kneel down for you and go to him at once. (If you are afraid of failure, go to 3- 1 and get the rocket launcher. )
