An idea I have for new special infected is called The 4-Eyes, because he wears glasses. This would be the most intelligent of all the other infected, so much so that he even still speaks English (sort of. He mostly babbles). He is also able to communicate with any other infected, and would use them to his advantage.
His power is that he is able to “rally” other nearby infected and have them fallow him, building up a hoard that he commands. And would use them more strategically, like for setting up ambushes, or send them after a specific survivor (like the one with least health). He could tell them if they should break down any doors/walls, or weather they should wait behind them. He would even teach them not to chase pipe bombs, and that they should walk around the fire, and not through it, along with tips like telling other flaming infected to get to water.
He is able to command and negotiate with almost all the infected, with the exception being the Tank (because Tanks don’t like to be told what top do).
