Hurry up, it's raid night

I came up with a way to get this done while getting all the research. You MUST pick up all research points.

1-3 are done as normal (in all about 45 minutes).
4. Smash and Grab
5-8. Do the first and second Hansen and Tosh missions in the order you wish
9. The Dig (30 minutes)
10-12. Do the first 3 Zeratul missions (the fourth one takes too long)
13-14. The Moebius Factor and Safe Haven (whichever order you wish)
15. Supernova
16. the Battlecruiser mission that follows, which unlocks Char.
17. First Char mission
18. Do whichever one you're more comfortable with dealing with; Air platform can be done in 20 minutes if you need more time
19. All In

You do Safe Haven both because it can be completed in 15 minutes (the first two Nexuses can be taken out by your starting Vikings) and gives you enough Zerg Research to push it to the top of the tech tree. You should have enough Protoss research by the time Char is unlocked via the Battlecruiser mission.

The second and third Zeratul missions can be completed in 10 minutes apiece (they can take an even shorter time if you weren't going after the research points, but that beats the purpose).

This method deliberately ignores the Rebellion missions because none of them provide a unit useful at Char. Going Ghost/Spectre provides no research points as opposed to Safe Haven, which also provides useful Vikings.

I would suggest doing "Gost of a Chance" also. No reseach points but 175K in credits to get thoese vital upgrades for tanks and air units. I did 20 missions and came into Char with 6:07 in total mission time.
