|Enforcer: Shotgun Skills||Tier 1|
|Basic (1 pt): When three or more enemies are within 18 meters of you, you receive a 15% damage bonus that lasts for 7 seconds.|

Underdog considers a player to be surrounded when three or more enemies are within an 18-meter-radius zone around the player and they're targeting him. Enemies more than 2.5 meters away from the player vertically are not considered. 
Because this skill requires the player to be close to several enemies, an active role in close-quarters combat is recommended. Weapons with a close effective range, like shotguns, are ideal for this skill. By the time the player is within range to use their shotgun effectively, the skill will trigger. However, longer range weapons, such as sniper rifles or assault rifles, can require more effort to utilize the benefits of this skill. Vantage points, due to their high level of vertical separation from enemies, are generally poor locations to attempt to use this skill.
In order to reap the benefits of this skill, it is required that the player be surrounded by multiple hostiles, which means that if one has no problem neutralizing his attackers, the effects of the skill won't be of much use. It is, however, quite handy to use when one is trying to revive a downed partner in the middle of a hot zone, as the aced skill reduces damage taken from enemy fire and the basic skill allows one to repel attackers more effectively.
- Underdog is a commonly used term to describe a team or individual that is greatly disadvantaged and/or expected to lose.
- The effect only lasts for 7 seconds but it will continue to refresh as long as the required conditions are met.
