When I was playing MW2 my dad rented for me, I played search and destroy, was the last one left with a riot shield so I planted the last charge and then I sat in a corner waiting, then this guy came and I just watched him the whole time, blocking his bullets. Once we won I was complimented on my play like "Yea that's how you do it Slugger!"
Edit: Im tired so I just fixed my grammar atm.
