(Capcom's primary storyline)
Arnold's team arrived in Raccoon City on the night Saturday 26 September as part of a major counteroeffensive against the Zombies, people who had been mutated and driven mad by the t-Virus. Unlike other U.B.C.S. teams, Arnold and his survived the week. Nothing is known as to what else the team did until the early hours of Thursday 1 October.
During the night, an experimental B.O.W. was stolen by a rogue Umbrella operator, Captain Rodriguez, and Arnold's team fell under the command of Tommy Nielsen, the executive of the dockyard it was stolen from. Arnold had little interest in his mission and had no respect for Nielsen, instead using the team's base camp on the highway overpass to shoot Zombies while his men laid out mines. During his recreation he shot Dr. Linda Baldwin, an Umbrella virologist, and when he realised his mistake decided against shooting again out of apathy. Not long after, Arnold got word on the radio that the US military was planning to bomb the city. After venting out his frustrations on Nielsen, Arnold finally gave up and left Raccoon City with his men.
As an NPC
Arnold will only be encountered in the End of the Road scenario if the player decided not to detonate the Tyrant's bomb collar before the encounter with Linda. Arnold should be treated as an un-killable sub-boss and regarded as extremely dangerous regardless of difficulty. Arnold will be located on the highway overpass above the area In front of Apple Inn and will shoot at anyone within his range. The bullets fired by his PSG-1 rifle deal massive damage to the player, sending them instantly into Danger status. This, combined with the fact that the area is mined with at least three landmines (which also send the player into Danger status), makes it one of the most difficult moments in the entire game.
However, there's a trick: the bullets are programmed to only hit on the fourth shot. Some characters can actually exploit this, such as Yoko and Cindy with their dodging moves. If timed right, the fourth shot can be avoided. Yoko can simply crawl away as the last shot is fired. Cindy can simply duck when the fourth shot is fired. If she is carrying Linda or an AI partner, they'll duck as well.
The player can also use Linda or an injured partner as a shield; right before the fourth shot, the player can grab Linda or the injured partner, and they won't be hit, but instead one of their AI partners if there are any left. Other than being in this area, he never appears again.
As a player
Arnold can be unlocked in Outbreak File #2 by clearing "End of the Road" scenario on VERY HARD difficulty. It can then be purchased for 5000pts. He can then be transferred to File #1 via File #2's data convert feature.
