Diablo Seco
From HellWiki
Diablo Seco is a (mostly) defunct radioactive power plant, populated by the mutated technicians and overseers of its former glory.
Enemies
The only enemies to be encountered in Diablo Seco are the area boss and a few semistrong enemies.
Technicians - These are the guy's you'll be fighting here, for the most part. Very little to no armour, armed with a sharpened fuel rod that does irad/stab damage.
Supervisor Marco - The big papa of Diablo Seco, wields a lasblaster and is actually a pretty legitimately tough fight.
