Summer Camp 3 is a four-trial event released during the Summer Camp 3 (Update). Each trial will last 1 week. The theme of the event is the same as the Summer Camp 2015 and 2014, it involves completing tasks such as killing a number of enemies or attaining a position in multiplayer while restricted to a category of weapons given in a week trial.
In a trial, only a specific types of weapon will be allowed for the player to progress through the event.
Complete 5 times: Finish first in Multiplayer (Free for all) using: see above.
During this event, many bundles and weapons were brought back in different trials that either offer protections against the weapons needed for that trial, or weapons that are needed for that trial (at a moderately cheap price).
For Trial 1 (Shotgun Mastery), the Aristocrat's Shotgun was brought back separately, along with the Shock Force Kit. Thus, it enrages many players as this is a cheaper way to obtain such a powerful weapon and having the S.F. Headset to boost its damage.
