Bugs

 * Sometimes after going through the back door at Helios One, he, Audaz, Basura, and 3 mole rats will attack you. There seem to be two ways to fix this. Try reloading the autosave. If that does not work, kill the mole rats, avoiding the dogs. Go inside and wait until you are [HIDDEN]. Then return outside and the dogs should be friendly again.

Behind the scenes
'Colmillo' is Spanish for 'fang'.
