Tips and Strategy
Legion can have great DPS as long as you aim for crit spots and manage your ammo and abilities properly.
Legion is a tank class titan which means he has a large amount of health.
Smart Core gives you unlimited ammo for 12 seconds and an aim bot. Be aware though that it only targets one entity at a time. The priority list is Pilots > Titans > AI.
Legion is an Ogre class titan, has large crit spots and is generally slow.
The Predator Cannon takes time to warm up and once warmed up slows legion down even more.
You cannot melee if your Gun Shield is up.
Gun Shield does not cover the entire front of Legion. Smart players will avoid shooting into the Gun Shield and aim instead for the still exposed areas.
Legion is slower when it's Gun Shield is up due to it automatically spinning up the Predator Cannon.
Legion's OS voice is male.
This Titan was spotted in official promotional material from Respawn. At the time, whether it was a work in progress, a name placard, or something else spotted during the video, it was safe to assume at that time that Legion (along with Tone) were new titans. This assumption was proved correct when Respawn announced all the Titans in video form.
On March 30, 2017, in the Colony reborn update, the prime titan for Legion was released. It's new execution is Legion hitting the doomed titan on both sides of its torso and then finishing it with a close range power shot.
