A good tactic is press square, and straight away press triangle, real quick. But make sure you only press them once each. Then tap the last square as much as you want till the combo is over.

Be patient, only pop out of cover for about two seconds before hiding again. Try and get an enemy in the center of your screen while in cover so that when you aim its easier to get them. Also, when enemies rush at you use blindfire a lot, using a shotgun is great for this as it just takes one carefully placed blindfire shot to kill any ambushers, and you can use your pistol for aiming at everyone else. Also, use power weapons (M79, dragon sniper, wes etc) as much as possible, using them to take out as many enemies as their ammunition amount allows, before going back and taking your normal weapon again.
