The Camp

The Camp is infested with soldiers and the 'dangerous' baddie for this area are Gattling Soldiers. That being said you have to be careful since these are the strongest enemies yet and will kill you dead long range. There are a small buildings that are good areas to hold up and fight off the waves of Soldiers so I suggest raiding the level for goodies then retreating to one of them.

Leon:

Leon's survival in the Camp is entirely based upon intelligent use of ammo and the suplex attack. If you can take out enemies with as little ammo wasted as possible as well as using the suplex attack whenever the chance arises you should easily be able to survive the onslaught of enemies. Conservation and intelligence is key in this level so be careful and slightly stingy.

Ada:

Ada is a good match for this level. Once you've raided the area for goodies her SA Rifle is very handy at keeping enemies out of your base. It is also quite effective against the Gattling Soldiers. Just be very, very careful about her lack of stamina or you will die very, very quickly.

Krauser:

Yeah, so, you get the drill by now. Just keep an eye on Krauser's health and ensure you don't get into trouble without the arm powered up and you'll have absolutely no problems with this level.

Hunk:

This is a good level for Hunk, his TMP and neckbreaker are extremely useful in this situation. As per usual just find a place to hunker down and murder the Soldiers as they come. Just be wary of the Gattling Soldiers and you'll do fine.

Wesker:

Wesker is a bad fit for this level. For some reason Gattling Soldiers can take a lot more Magnum ammo than they should so you'll find yourself wasting a lot of it. Wise usage of Wesker's supply of grenades should allow you to survive this with no real problems. You just may have a bit of trouble hitting enough points for five stars.
