If you attack enemies with a melee weapon you will be able to knock them to the ground and from there follow up with a trample attack to deal damage to your foe. This however is not the most effective method of attack as it takes several strikes with your melee weapon before you will be able to successfully drop your foe to the ground. It is more effective however to use sliding to knock enemies down, this maneuver is executed as you run by pressing the L3 button to perform a slide which will easily take down your target and allow you to finish them off with a trample attack. The advantage of using sliding is it requires no weapons to be equipped making it a useful move when you do not have a melee or ranged weapon and it also enables you to save bullets. However, it is advised that you only use this form of attack during 1-on-1 situations as trying to use this attack against multiple enemies is extremely dangerous and liable to get you killed. Sliding only works on human enemy infantry.
