DetailsImproves the effectiveness of the Interrupt Attacks.

Sure Strike is a Assault/Raptor class perk available from the start.

The Sure Strike perk increases the damage for all stun attacks, but more importantly, causes even the first Interrupt Attack (the backhand punch with the left hand) to cause a heavy stun on the victim; the target will stagger backward rather than just a short flinch.

There are two levels of severity that a player can be stunned by: light and heavy. A light stun causes a Marine to appear as though he is flinching. A heavy stun lasts longer, and the Marine visibly staggers.
