CrossFire China || M4A1-S Under Tech + Variants (Showcase)
Quick look at the specialized assault rifle in Zombie Mode - the M4A1-S Under Tech. Again, it is way heavily modified in terms of the models. What's cool is that you can shoot laser in Zombie Mode when fully charged. What's more interesting that the laser beam can heal yourself and your teammates if you shoot the laser at them, and the health point depends on the variant (4HP for the stock, 6HP for the Silver and 8HP for the Gold per shoot). Overall, this piece is a great improvement for those who prefer to be "Medic Guy" in a match. It's even better when it can be obtainable for free.
