Belly of the Beast, part 4 | Campaign - Final missions SC II: WoL Guide
Last update: 11 May 2016
Accordingly to the plan, the three explosions have caused the tunnels to be flooded with lava. It's a problem for Raynor and the company as well, as they need to quickly run and get to the surface. You will have to hurry, as the paths are starting to disappear under magma and Zergs are still roaming the area.
[#17]
As only the fourth, rather short stage begins, start running to the exit. There will be in fact only two groups of enemies that will try to stop you [1], [2] [#17] and whether you want it or not, you'll have to face them. In the first case, expect some Nydus Worms and eggs in the area. Later on, beware the Infestor.
[#18]
At the last straight, you will also have to face an Aberration [3] [#18], but by then probably nothing will stop you from leaving the unfriendly tunnels [4].
