Belly of the Beast (Achievements) | Campaign - Final missions SC II: WoL Guide
Last update: 11 May 2016
Belly of the Beast:
Plant Seismic Charges at the 3 Fissures, Escape The Cave.
Unbreakable:
The objective is rather obvious. Once your heroes receive enough damage, they don't die, but faint. You of course have to avoid that. Such a situation is especially possible with the charging Banelings (second cave) and while meeting the Queen (third). Details can be found in the mission description.
One Shot Fifty Kills!:
A real challenge, which you should try to complete during exploring the cave full of infected Terrans (the second one). The most important spot is marked on the map as [3]. There you will find a whole bunch of mutants, which will rush in your direction after discovering Raynor and his companions.
To gain the achievement, you not only have to shoot the incoming horde (though you might get lucky). In most cases you will be lacking a few, so you should use another method.
The path leading to the infected horde is straight and long. Grab Raynor and place him above the characteristic orange crystals. Tell him to hold this position so he doesn't move.
You can send the Marines and Medics away, as they aren't needed in this solution. Do the same with the other heroes, leaving at least one of them in the area. Use him to provoke the infected Terrans, though don't attack them. Run with him between Raynor and the group of enemies, trying to survive for as long as possible (keep on giving the move command). The objective here is to make the Zergs form a dense group. Once the hero faints, they will rush onto Raynor. Let them attack you and shoot right before fainting. That way you have a much bigger chance of shooting 50 than you'd have normally.
