Watch Starship Troopers: Invasion Online

After the events of Invasion, Johnny Rico has been demoted to the rank of colonel and relocated to a Martian satellite to train a new batch of troopers. Unfortunately, these troopers are some of the worst low-performing Rico has ever trained as they're Martians and don't take the war seriously. Mars overall has low support for the war as they see their planet unaffected by the bug conflict and even suggested pulling out from the war. Because of their laid back attitude, the denizens of Mars wasn't ready when the bugs attacked. Unknown to everyone, Sky Marshall Amy Snapp executes her plans for power.

Warden stationed in Fort Casey evacuate along with the survivors and bring military intelligence safely back to Earth. Carl Jenkins, now head of the Ministry of Paranormal Warfare, takes the starship on a clandestine mission before its rendezvous with the Alesia and goes missing in the nebula. Now, the battle-hardened troopers are charged with a rescue mission that may lead to a much more sinister consequence than they ever could have imagined...
