In Resident Evil: Operation Raccoon City for the PS3 and Xbox 360, killing Leon is like putting Tony Montanya down! You wanna play rough? Ok, he plays rough.
To send this fool to undead hell, you need to do a couple of things:
1. Immediately kill the two guys that turn on you.
2. Grab the heavy machine gun on the left fence and light him up until zombies spawn.
3. When you get the chance run about midway back and stage right is a box with a precision rifle. Grab it!
4. Wait for Leon to shoot, then put about 2-3 bullets in his ass before he throws the grenade.
5. Dodge the grenade.
6. Wash, rinse, repeat. You may have to move up to get zombies to spawn and screw your team
mate. No reviving anyway.
7. The whole process should take about 5 minutes.
8. Enjoy the ending!
