The Defense Cannon is a weapon in Just Cause 4.

Description[]

It's a type of artillery.

It is by far the largest type of automated gun turret in the known Just Cause Universe. It looks like a normal cannon with some additional sheet material covering parts of the barrel. It has an enormous barrel diameter of about ~700-900 millimeters.

Using the AR lens on the cannon will yield a box with information stating:

"DEFENSE CANNON"
"Indestructible."

Technology[]

It looks like a normal cannon with some additional sheet material covering parts of the barrel.

There is also a sticker/plate on the back of the base of the cannon which says it uses radioactive material, although it is not known which element of it involves radioactive materials specifically. Or even if the gun mechanisms require this, or if the fired munitions are radioactive.

When the cannon is about to fire, the barrel of the cannon will have a red glow and it will make an humming charge-up sound. Because of this, it is speculated to be a railgun, which means that it uses electromagnets to propel a metal projectile.

Although not seen in the game, according to general Rojas, the "override" of the cannons at Prospero Aeroespacial can be "remotely enabled". This suggests the guns can be manually directed to fire at the base itself, which is something they normally do not damage.

Performance[]

These turrets are completely invulnerable to damage and cannot be grappled. Thankfully, these cannons are easy to avoid due to their large size and slow movement. Also, despite the enormous size of the barrel, they have as few range as the SAMs in SolĆ­s.

These massive guns are powerful enough to destroy anything and everything destructible in usually one, but at most two to three hits. They can destroy any tank in the game (and the Spearhead Transport) with 1-3 hits. No destructible object can survive a direct hit from these guns.

Normally they are incapable of hitting Rico when he's moving, however if the player should stay at the same place (or small area) in a cannons field of view, they can almost kill Rico in one hit. The damage output is far greater than Rico's HP, but his plot armor allows him to survive any single source of damage, except falling from high altitude.

In region strikes at bases where these cannons are, these cannons can prove fairly dangerous until the mission is over or at a certain point in the mission where they are deactivated.

The turrets are unable to hit anything too close to themselves, so it's safe to stand nearby.

The Defense Cannons at Nodo Defensivo Uno, Dos and Tres are much stronger, firing long bursts with a short delay in-between. These particularly powerful cannons (in combination with a lighting-blizzard hybrid storm) are designed to prevent the player from entering Illapa and the surrounding area before Operation Illapa.

Trivia[]

  • After taking over certain bases for the Army of Chaos, the turrets will attack Black Hand units.
  • While this cannon should certainly kill Rico in one successful hit (it can destroy targets much stronger than Rico), Rico absorbs only a fraction of the damage (and ignores the rest of it), just enough so that the player can barely stay alive. This is a purposeful game mechanic by which nothing can 1-hit-kill the player.
  • About the radiation symbol: There have been multiple types of real large-caliber artillery guns that were designed to fire tactical nuclear bombs, but there is no indication of the fired munitions in the game being of that type.
