On doing the final bosses once again (getting me more achievements) Psy and myself noticed that on Sheva's tribal outfit she is infact wearing a white thong under the skirts we noticed this because during the scene where Chris must save Sheva from certain death the camera pans up and gives a perfect up skirt shot we felt this must be shared with you. Also anyone having trouble getting the "lead asprin" achievement try using Jill BSAA for mercs because her handgun has the highest headshot critical ratio I've seen on any gun, pretty much shoot a zombie in the face it's a exploding skull job.
