Anti-ICE gunman Joshua Jahn spent 17,500 hours playing violent videos games

Video game-obsessed gunman Joshua Jahn’s nearly 17,500 hours of online gaming were largely spent in “first-person shooter” games aimed at killing enemies, according to his Steam account online.

Since account was opened in September 2011 — he logged 729 days worth of game playing, more than two years.

That amounts to nearly 15% of his entire life — including sleeping hours — on the video game platform Steam over the course of a decade and a half.

The 29-year-old, known by his online pals as “SAM I Am” and “Frank Hoenikker,” spent nearly 7,000 hours in the open-world survival game “Rust,” his online profile detailed.

“Rust” pits players against each other to survive the harsh environment.

He fixated on the 2007 FPS release “Team Fortress 2,” logging 3,400 hours, last playing just hours before he opened fire on the Dallas ICE Facility, killing one and seriously wounding two others.

The crazed shooter targeted an ICE bus that was transporting several detainees and agents into the sally port at the field office Wednesday morning.

He killed one migrant detainee and critically wounded two others when he began firing wildly into the facility. No law enforcement agents were injured.

The gunman’s second-most-played game was “Ark: Survival Edition,” spending 3,500 hours, or 140 days, on the dinosaur-based survival game.

Jahn spent another 50 total days on the zombie-apocalypse shooter “Left 4 Dead 2,” unloading another 914 hours in the physic’s sandbox “Garry’s Mod.”

Jahn had a total of 34 games added to his account at the time of his death.

He also played popular titles including “Grand Theft Auto V,” “Rocket League,” “Counter Strike” and “PUBG.”

His profile was listed as Frank Hoenikker, a reference to Kurt Vonnegut’s character in his satirical post-modern novel “Cat’s Cradle.”

Jahn briefly played as the name “#Impeachment,” between Dec. 15, 2019, and Sept. 18, 2020, correlating with the first impeachment trial of President Donald Trump.

The anti-ICE shooter was part of four gaming groups on Steam, including one with only seven other members.

“Fug bithces Get Money” as the gamers’ called it, mocked Jahn’s shooting skills after he was idnentifeid as the killer.

“[He] shoulda hit the range a lil more,” one member wrote in the gaming group chat on Thursday.

“He missed,” the user exclaimed.

A third comment greeted the “chat” with an emoji of a red character missing its head.

Jahn was also awarded the “mind blown” award on his Steam game account. The FBI said he killed himself with a self-inflicted gunshot after firing multiple rounds.
