Many jobs in Payday 2 can be completed in stealth. If players avoid getting caught on camera, evade or silently kill security guards, and keep any civilian witnesses from calling the police, the alarm will not be raised and the players will receive an experience bonus. Otherwise, players will have to achieve their objectives, carry out any loot they find to a dropoff point, and then reach their escape point under the pressure of constant police assault waves. Most of the enemies are SWAT units sourced from DC Police, then FBI SWAT, GenSec private security contractors and finally the DHS as difficulty increases. Mixed in with these are special units; all versions of Payday 2 include the “Shield” and the “Taser” – both named for their signature equipment, the “Bulldozer” – a SWAT team member in a modified near-bulletproof bomb suit, and snipers. The Crimewave Edition and PC version include the “Cloaker” – an infiltration and hand-to-hand combat expert. Exclusive to the PC and Crimewave editions are near-indestructable SWAT van turrets, capable of area denial, a medic capable of returning an enforcer to full health with no status effects, and Captain Winters, a well-protected veteran police officer who sustains assaults and buffs enemies until he can be driven off.
