Investigation in Guadalajara

At some point in 2018, reports in Mexico indicated that a research lab, rumored to be owned by Desperado, had circulated, especially after toxic waste was issued in the sewers of Guadalajara. Maverick, having already taken care of the Abkhazian Coup, deployed Raiden to investigate the lab for any evidence implicating Desperado.

Raiden, upon arriving at the border, purchased a disguise to blend in with the civilians so he wouldn't stick out, although he ended up being tricked by the salesman into wearing a mariachi costume. Upon arriving at Guadalajara, Raiden also revealed that he brought Bladewolf along in order to throw the newly reconstructed UG a bone. Upon arriving at the insertion point, he entered the sewer system, although not before being spotted by two locals who witnessed the entire thing due to mistaking him for a Mariachi singer, although they decided to forget they ever witnessed it.

Afterwards, Kevin briefed them about trying to locate the lab in the sewer, and also warned him about locals commenting about "black crocodiles" living in the sewers. Bladewolf then proceeded to scout ahead of Raiden, also informing Raiden of there being UGs patrolling the area shortly thereafter. Raiden then ended up ambushed by a Mastiff humanoid UG, forcing him to destroy it before it could alert his presence to the other UGs nearby. Afterwards, Bladewolf reported the presence of catwalks for Raiden to avoid UG patrols if necessary. Afterwards, Raiden entered another area of the sewers before Bladewolf reported the presence of a boy in the sewers and his being attacked by UGs. Raiden then rushed to stop the UGs.
