One of the coolest aspects of Operation Raccoon City’s multiplayer is its three-sided battlefield. Umbrella Security Service members, who are there to cover up the zombie outbreak, clash with Spec-Ops soldiers sent to get answers and figure out exactly what went down. While those two factions bicker and trade shots, zombies and BOWs wreak havoc all around, targeting anything with a pulse. 

Thanks to the campaign story, we get to spend some time with the USS and, even though  they’re technically the bad guys, relate to them on some level. But what about those Spec-Ops folks? Well, they’re going to be playable in a free DLC mission coming April 10 to Xbox 360 and PS3, one that just so happens to revisit an important moment from Resident Evil 3…

This free mission features not just the Spec-Ops squad (most prominently seen in the incredible Triple Impact trailer ), but also recreates the scene where Jill Valentine must escape the rampaging Nemesis. So we get a shot at new characters, plus a chance to see an old favorite caught in the middle.

But who are the Spec-Ops characters, anyway? Why I’ve got these official descriptions right here:

Dee-ay

Crispin ‘Dee-Ay’ Jettingham has been a soldier for as long as he can remember. He was the government’s top choice to be the leader of the Echo Six team. Always calm and collected, he is a true soldier and is highly skilled and efficient with his weaponry and his orders.

Harley

A foul-mouthed ex-biker, Erez ‘Harley’ Morris joined the service to avoid going to jail. Excelling in medicine during operation Desert Storm, Harley unexpectedly became one of the best medics in the field. Always putting other’s lives before his, he will always do his best to make sure no man is left behind.

Party Girl

Sienna ‘Party Girl’ Fowler got her reputation throwing wild parties in her youth for businessmen and officials. Little did they know that every party she threw was also recorded with hidden equipment, which would be sold to the highest bidder. The government hired her after she managed to dupe their top surveillance expert at one of her parties.

Shona

Exposed to death at a young age, Lawrence ‘Shona’ Kimbala began treating diseases in his home country of Zimbabwe. After his father’s death, he attended Harvard medical school where he realized he had a skill for controlling viruses instead of curing them. He joined the Army’s special weapons program as their foremost expert in virology.

Tweed

Marissa ‘Tweed’ Ronson has a quick tongue and a ready fuse. Originally working for the British Secret Service, she disappeared after a bomb removal operation left her scarred. Hand-picked by the government, Tweed became part of Echo Six because of her un-paralleled expertise in demolitions.

Willow

Caroline ‘Willow’ Floyd developed her skill for speed and elusion growing up alone on a reservation in Montana. She joined the Army straight out of school, excelling as part of the Special Forces. Never satisfied with herself, Willow continues to hone her skills each and every day.

Resident Evil Operation Raccoon City hits the US March 20, following in EU on March 23. The PC version follows on May 18.
