Where is the Skull Probe? Why am I not getting the option even after I researched it? Where is it? What am I missing?

Seriously, I'm so ♥♥♥♥♥♥♥♥ frustrated because no one seems to be having this issue. Even the newbs somehow figure it out but nobody's pointed out how exactly to get the Skull Probes. I freakin' hate the early infiltrators rush, but I hate the fact that no single clue is being given about the Skull Probes other than the fact that they exist even more. Just HOW DO I GET THEM?

You can build them at Listening Posts.

Your mistake lies in the fact that you are playing an EXPANSION, not the base game, hence the base game's campaign teaches you how to get skull probes as well as their purpose (increase sight range and detect infiltrated units). All you have to do is build a listening post and then skull probes are available to be built from the listening post. The research at the stronghold causes skull probes to INFILTRATE, so no point in researching it unless you have a strategy in mind. You are allowed to build a maximum of 4 skull probes.

Infiltration rush is worthless (in other words it's a noob trap), once you know someone is using infiltrated units all you have to do is have detection and focus the units until they die, because generally most infiltrated units are weak (excluding Chaos Marine Tacticals).

Tl;dr There is no issue with the game; you are new, and learning the ins and outs.
