I got this list of some cool strategies to use when playing Manhunt :
The team works alongside each other while seeking and killing the opposing team. This usually includes communication through headsets or simple instinctive ganging-up on a tough defender.
If all four players on defense stick together, the best choice is for all the hunters to stick together and hunt as a group as well; the key is waiting for everybody to be in position and coordinating attacks to avoid being caught in a stun trap.
Safety in Numbers
The defenders all stay in a large group, or in smaller groups close to each other. When an enemy has been spotted, every defender will focus on stunning them or disabling them in order to gain points or help their teammates escape.
Also referred to as "Stun Locking". This usually works best with a group of two or three defenders. When an attacker has been spotted and comes close, one of the defenders can either get a stun or throw a Smoke Bomb and stun the pursuer. While the pursuer is on the ground, a different defender can wait by them and stun the pursuer again without the use of any abilities.
A pursuer can be stunned several times in a row by defenders that alternate their stuns. This is repeated until the attacker gives up and respawns (by pressing the Triangle or Y button) or if the attacker's teammates arrive to help their comrade. Another effective technique should you choose not to respawn or your teammates are unable to help you is to have the perk Resistance. Resistance allows you to get up quicker after being stunned and therefore interrupt the rhythm of a stun lock. However, in doing this you risk not getting your contract quick enough and therefore being stunned again.
