EPTNot sure if it is worth a separate topic, but haven't found the proper one to post this.
Lock & Load Co-op mission is the only one in Cooperative which allows speedruns - all other missions have their scripted duration which depends on the mission difficulty.
I'm playing a lot of Co-op and recently discovered that literally nobody knows about the easiest speedrun for Kerrigan & Zagara duo. To complete this mission in 3:30 game time / 2:30 real time or faster you should just make overlord speed for both players & send 1 ovie to each control point, avoiding enemy units. The idea is that no enemy units are standing on control points until Amon sends troops to capture them so all points are free to capture in the beginning. Complete instructions are shown in this video:
Overlords should be sent like this:

The first wave hits only around 4 minutes mark even on 15 lvl / 15 lvl Brutal so you can win the mission easily even not executing this technique perfectly.
Other heroes may also be able to speedrun this map with proper units (observers / phoenixes for Artanis, wraiths for Swann, called banshees for Raynor, corsairs for Vorazun - Karax seems the hardest one) but probably not on Brutal as you may need more time to build those units. Anyway this speedrun seems to be the most time efficient way to level up your heroes if you don't want to play on low levels for whatever reason.
Let me know if you have any questions & enjoy your almost free XP!
Ye I had similar thoughts about this level being great for leveling. With Karax and a good ally I was doing the map in 13 minutes. This is a lot better that even what i was doing. Great post too!![[image loading]](http://i.imgur.com/kSrrkgZ.png)
