Step 4: Now what??
Next, decide what are you going to boost? do you want headshots? just kills? Nukes?!
Then set your kill streaks accordingly.
For example If i was going to Nuke boost i would set my kill streaks as Harrier, Pave Low, and nuke (duh). the reason i would pick Pave over Chopper Gunner is because while your Pave Low is racking up kills you can continue to boost.
