i can remember insertions down against us when we played $H!T at domination - does work as you can push the enemies spawn point back depending how far up you have em - i feel as though the spawn points on black ops are worse than any other game ive played on - they certainly do spawn right behind you - anyway yup its a good idea just i aint spending 2,000 on insertions yet - got more guns to unlock and other shizz
