The entirety of the kit is trying to take the chaotic nature of Hotline Miami and implement in SS13, where chaos and the such are no stranger. You unlock masks throughout the game that give you unique effects like taking more damage before you die or only being able to use your fists but you deal more damage or you throw weapons harder. Everyone dies in 2-3 hits including yourself. If you haven't heard of Hotline Miami or don't know much about it, it's a fast paced top down game where you run and gun murdering people mercilessly at mach speed. The entire traitor kit is based upon Hotline Miami's mechanics.

Also you have a permanent drug effect while wearing the mask to really incite that aesthetic. For example the owl mask gives you thermal vision, pig mask takes slightly less damage, tiger mask doesn't let you use guns but increases your damage. In addition to the damage bonus each mask gives you an increase in speed while worn and each has a random unique effect. Every mask makes you deal 4x damage while equipped, however you yourself will also take 4x normal damage. The Hotline Miami masks are part of a 20TC traitor kit that when bought will give you one random mask out of six available and a syndicate brand jacket.
