Call Of Duty: Modern Warfare - 14 Tips & Tricks The Game Doesn't Tell You

3. Use The M4A1 Assault Rifle

By far the best gun in the game at time of writing - judging by how every player under the sun is using it right now - is the M4A1.

Besides having plenty bang for your buck, the general weight and feel of this rifle lets you line up shots without going past your target too easily, and for me at least, was where the game started to properly "click".

Unlocked at level 6, equip this thing and get to grabbing the rest of its attachments. I have had the most kills with an M4A1 by far.
