Richard Aiken was the communications expert for the S.T.A.R.S. Bravo Team. He also supplied communications for the S.T.A.R.S. Alpha Team. He also makes a brief cameo in the Resident Evil prequel Resident Evil 0.
After being attacked in the Raccoon Forest, Richard escaped to the Spencer Mansion along with other S.T.A.R.S. members. Later on he found Rebecca Chambers sleeping in one of the bedrooms in the estate and tells her they need to find a safer place to stay. The proceeded to the attic where they would contact the rescue helicopter. On their way to the attic they were attacked by a giant snake called the Yawn. During the battle Richard sacrificed his life in order to save Rebecca. He was bit and poisoned, he is found by either Chris Redfield or Jill Valentine depending on the scenario. In the original version of the game he dies where he is found regardless of whether or not you give him a serum in time. In the Gamecube remake however, if you give him the serum in time, he will live a little longer.
In the Gamecube version, if he is given a serum before he dies his death will play out differently (depending on who the character is). In Jill's scenario, he helps fight the Yawn once again. When the Yawn goes to attack Jill he sacrifices himself once again and is eaten by the snake. In Chris' scenario, he helps Chris for a short time and then helps him fight the Neptune (a shark like creature). Just like in the Jill campaign, he sacrifices himself by pushing Chris out of the way of the Neptune and is eaten.
