Bile Titan

The Bile Titan is a massive, heavily-armored Terminid that appears to be the final growth stage of a Bile Warrior. They can be found on Challenging difficulty as an Elimination Target and begin to spawn naturally and more frequently as difficulty increases.

Despite its size, it can quickly catch up to Helldivers, spewing its lethal bile onto them. Helldivers near it can also be crushed or speared by its hulking claws.

WARNING: As the name implies, Bile Titans are massive. Though they can be destroyed, their death throes are no less dangerous than the attacks they unleash whilst alive; oftentimes a Helldiver who is unfortunate enough to find him or herself underneath a Bile Titan as it is falling will die outright from being crushed.

Sometimes, after it falls, post-mortem muscle twitches cause unsuspecting Helldivers to be launched far distances due to a strange interaction with the legs of dead Bile Titans, just be careful when navigating their carcasses.

Tactics

 * Bile Titans appear naturally on the Extreme difficulty level and above while being assigned their own special mission on challenging. Bile Titans are enormous but still move quickly, and behave similarly to Bile Spewers, spitting out streams of corrosive bile at their target.
 * Keep as much distance from them as you can. A single melee strike from a Bile Titan can one shot a Helldiver, or at the very least bring them down to a sliver of health.
 * If you cannot run, staying beneath them for short time spans is also relatively safe, just watch their legs and ordnance heading towards it.
 * Use the terrain to your advantage. While it can climb over most terrain, its attacks can be easily dodged with cover
 * Bile Titans are immune to stun grenades and EMS strikes. Do not rely on either to contain and control them.
 * Work with teammates to bait it, allowing some of the team to target its weaker spots while it focuses on another team member.
 * Run away; light or medium armor will not inhibit your speed enough for a Bile Titan to catch up to you.
 * Throw-and-forget precision stratagems such as the Orbital Railcannon Strike, 110mm Rocket Pods and the Orbital Laser. All of these have the potential to kill a Bile Titan instantly if they destroy its head, but will most likely only grievously wound the Titan.
 * If the titan is still standing afterwards, it often takes a single shot from an EAT-17 or weapon of comparable power to bring it down.
 * The detonation of a NUX-223 Hellbomb, SEAF Artillery: Mini-Nuke, or Eagle 500kg Bomb will kill a Titan outright, assuming the Titan is within the epicenter of the blast.
 * Wrangling a Titan's unpredictable movements through heroic acts of kiting/self sacrifice/mass self sacrifices are often required to accomplish this.
 * The Titan's bile vomit attack leaves it open long enough for an Eagle 500kg Bomb to be used against it. Goading it to spew on you, throwing the Eagle stratagem underneath it, and dodging the bile at the last second, is a reliable way to kill a Titan up-close. It is recommended to throw it near the torso to ensure adequate time to run away from the blast zone
 * High-Explosive Anti-Tank weapons such as the FAF-14 Spear can kill Bile Titans in one hit whilst the EAT-17, LAS-99 Quasar Cannon or RL-112 Recoilless Rifle are capable of beheading a titan in two hits.
 * However, with pinpoint accuracy from a dangerously close position or a good amount of what veteran Helldivers call "luck", any of these weapons can kill a titan with a single shot squarely in the mouth.
 * If you die, you can attempt to maneuver your Hellpod to strike it on the way back down once you are called back into the fight.
 * The Bile Titan has two sacs under its body, one under the abdomen and the other under the thorax, destroying both of which will prevent its devastating spew attack.
 * Rockets fired from the Patriot Exosuit can kill the Titan with two hits to the head. Alternatively, one could barrage the Titan with 5-6 rockets to kill it from any angle.
 * Bile Titans can (and often will) emerge from bug breaches on Extreme difficulty and above, so preventing or neutralizing those quickly becomes much more vital. Thankfully there do appear to be some limitations on how many can be spawned this way at once, but an out of control swarm can potentially just bring in more whenever one is killed.
