If you want to get better never underestimate the game play in easy.
1: I learned how to melee with deadly position, and doge the onslaught of ammunition flying toward you.

2: Be proficient enough with any weapon to get to a spec. weapon. (a Spec. weapon is any weapon others hate you having).

3: Always test the time between the throwing of a grenade and the animation on high lag servers. This little mistake has cost me huge amounts of kills.

4: Don't be afraid to play against High skill players, most of them are quite happy to show some of there tricks.

5: Play against your mates as often as possible so as to find their weakness and while your at it find your own.

6: No matter what NEVER lose your cool, if you do you will miss more often and will make more mistakes.

7: Never underestimate the power of newbies in large groups. (20 out of 100 bullets wont do much damage but 200/1000 will)



---------------------Snipers---------------------


1: Take your time to learn the power of your rifle.(Halo EC the sniper is stronger than the ones in Halo 2)

2: Find the one shot kill zone on all units.

3: Try to stay hidden. (remember that you leave a bullet trail that will give a good indication to where you are standing)

4: If you have time to set up the one hit kill do so. If the target is moving make your adjustments and aim for the body.

5: If you are found do not return to the same spot striate away. (now that your opponent knows where you are and how to get you out)

6: Always carry a mid to close range weapon as back up.
