I have discovered my own tactics I use but am curious to see if anyone has anything else I have not discovered that is effective. Boomer 1. Always vomit from above when possible and live to puke another day. 2. Remain hidden until you are actually ready to vomit. 3. If you have to attack, do it when you are sure a stray bullet will hit you and in range of the most survivors as possible. Smoker 1. Holes in ceilings are your best friend, try and snag the #4 survivor jumping down. 2. Time your attack with the boomer as players covered in goo have a harder time reacting to your own mayhem. 3. Snatch survivors who are helping other survivors. Hunter 1. Great for taking down stragglers, players who wander off alone or lag behind fear the hunter for a good reason. 2. Zig zag jump towards survivors not directly at them unless they are really close or have not noticed you. Tank 1. Try and get one survivor in red and crippled to where they cannot get up, then attack another. Basically try and cause separation between the survivors so your teammates can take down enemies individually. 2. Avoid chasing green health survivors, instead hit them with 2ndary ranged attacks then followup with a punch and repeat. General tactics 1. Use the witch as cover, same with cars with alarms, if you make yourself a target usually theres at least 1 dumb survivor who will shoot and cause your little friends to swarm. 2. Coordinate your attacks with your teammates, if you work together and time your attacks you can win rather easily. A single or even 2 infected are no match vs 3 or 4 survivors, timing is the key.
