Alternate guard actions in Vertigo
During the mission you will reach a Spiderbomb path on the second mine level, near the wall up to the third level. If you send the Spiderbomb up this path, it will open a door to a weapons cache and give you the chance to take out several guards quickly. If you kill them, the next time you attempt the mission, there will be three guards in position by the spider hole.
