So what are your tips for using special infected in versus? Most of us probably know that attacking on your own as soon as you spawn usually doesn't get anywhere.

Spitter

Most people spit at moving survivors, but this rarely works. Spit is most effective to:
If a survivor is down you get maximum damage as they can't move out the way. If other survivors are nearby, wait until they start helping them up to spit to force them to drop. This means you get maximum down time for the single survivor.
If there is a room with some corridors, allow 2 survivors through then spit at the floor to block the other two. Sometimes the other two decide to wait, and the forward two carry on relentlessly and don't wait. You then have an effective gap and your team can attack the back group all together which makes it a lot harder for survivors to cope.
Self explanatory!
that much damage while incap'd. It's however quite effective to keep the other survivor from getting close enough to help him up. The extra damage is just a bonus.
