- "Okay, you're in position. Remember, your codename is Vandal. Under no circumstances, tell anyone your real name, understand? Your voice filter will keep you anonymous if you meet anyone."
- —Tyler Radikov to Vandal.
Though very little is known about Tyler's life, he does mention that he was born on Mars and thinks little of its living conditions.
Titan Station OutbreakEdit
Tyler and Daina Le Guin are among the Unitologists who participate in the sabotage of the Government Sector and the provision of false information to recent Unitologist inductee, Karrie Norton (codenamed "Vandal"). Tyler purposely tricked Vandal into performing tasks that, unbeknownst to her, aided in the spread of the Necromorph infection upon Titan Station's different sectors.
Some of the things Tyler had Vandal do was sabotage power boxes to cut off communications, unlock doors to different sectors. Tyler promises to walk Vandal through her mission “every step of the way" before he is "cut off" from Vandal when she is on the tram to the Crossover Tube. He regains communication in time to tell Vandal that he knew nothing of the Church's plans and wished to help her escape.
Tyler’s tips during Vandal’s battles suggest he’s had encounters with Necromorphs, previously. When coming across the first Brute, Tyler tells her he came across one before and gives a detailed description about its front armor and to aim for its weak-spot on the back. Though he claims to have had contact with the Necromorphs, he doesn't seem at all affected by the dementia brought about by the Marker. He dismisses Vandal's dementia, claiming she's being "hysterical" and that she should focus on the mission.
A notable trait Tyler carries as a character is his direct sense of humor. When he is in the process of unlocking a door that is impeding Vandal's objectives; he lies to Vandal, telling her that she will need to take an alternate route. He goes into detail, telling Vandal how many meters she must trek. At her apparent disbelief he simply tells her he was “screwing with her” before opening the door to the next objective. At one interval during the game, Tyler comments that he should have a nickname similar to "Vandal", and remarks that his should be "The Russian." When asked for an opinion, Vandal simply remarks that Tyler is being stupid. As to why he chose that particular nickname is unclear.
Tyler combats the efforts of Hans Tiedemann’s aid to Vandal in repairing the station, changing the coordinates to her locator to keep Vandal on track in sabotaging the station whenever the station Direction changes her course. He betrays her a final time when he tells her shutting off the power to the station's doors would trigger the emergency quarantines, thus locking the doors between sectors. He congratulates her in her efforts and tells her she'll be remembered for her actions.
After Vandal’s battle with the Necromorph overheating the power core, Tyler reports that the sabotage of Titan Station was successful and he was "coming home".
