This thread is basically some advice for those playing through the SC2 campaign for the first time. When you get to the end section of the game, you are warned that if you choose to continue, you will not be able to visit any other planets or missions that you haven't already done. Once you complete the campaign, you can freely replay levels you have previously beaten, but you are unable to visit new levels.
This includes the secret mission which is unlocked on the level Media Blitz - in the south-east corner of the map, there is an SC1-style Science Facility that when destroyed will unlock the secret level.
For the protoss levels, at least one person in these forums wasn't aware that there are actually 4 protoss levels available, because this is not entirely obvious within the game itself. After you finish the first mission, simply click on the crystal to get to the later ones.
If you fail to access the secret mission or the protoss levels and you finish the campaign, the only way to get access back to these levels is to start a new campaign. It took me about 2 hours of playing from the start of a new campaign, using the godmode cheat, to unlock the secret mission, so it's better to do it on the first play through.
Further discussion on the secret mission - mild spoilers
The secret mission itself is probably one of the funner levels in the campaign. It harks back to the old Installation-style maps from SC1 with a squad of marines and Raynor leading, with interactive things such as surveillance cameras and turrets you can take control of and special collectable ammo and ability upgrades for Raynor
Storyline spoilers for secret mission
There are hybrids in the test tubes, as well as an actual hybrid itself, but again there is no mention of the UED or Duran at all? All of those scientists around the place fail to say anything either, which really was a lost opportunity - could've taken them captive and forced them to explain what was going on. Also someone else pointed out in the other campaign discussion thread that Dr Narud is highly likely to be Duran, so if that was the case they could've made it clearer that the secret lab wasn't actually Mengsk's work at all.
