Projectiles[]
Bullets
Bullets are fast projectiles that travel in a straight line. These are the only enemy projectiles with which enemies can't hurt themselves in most situations unless they are stunned or their bullets are deflected back at them.
Missiles
Missiles have either homing capabilities, fly in a wavy pattern or a combination of both. Missiles can be shot down with bullets and other projectiles.
Artillery Shells
Can be launched from an Artillery Truck or some other bosses like the Stealth Tank. They cannot be destroyed and have massive area damage. However it's possible for them to be deflected.
Airstrikes
A red line traces their flight path and a red cross to indicate where they should land. Like parabolic bombs they cannot be destroyed but most airstrikes only happen once meaning that if you return to a bombed area it's less likely for another airstrike to occur. They usually fly diagonally.
Grenades
Grenades can be thrown back with a melee button but if there are too many then you should run away. If you shoot the body of a Grenadier Mook it will drop a grenade each time. Some bosses also make use of grenades which are too numerous to throw back.
Acid Globs
Generally if you caught a hit from it then this means certain death unless deflected. All terrain except checkpoints and metal are no match against acid. If a boss is hit by one of these they will receive some damage too. Once they land they split into three smaller blobs which won't split anymore. Terrokrawler sprays streams of acid instead of globs.
Fireballs
There are multiple versions. One acting like airstrikes but they have a smaller splash radius and fall straight from the sky. Presumably summoned by Satan, as they appear (in a more numerous form) during his final stage. Another version is launched by the Bone Wurm and Satan when in second/third form, similar to the way the Terrorkrawler launches them.
Fire
Fired by Executioners. These can't be destroyed at all.
Reactions[]
Enemies have different reactions:
Attack/Alert
- This reaction is signified by an exclamation point above the enemy's head. Some of the enemies will put their gun in a firing stance. Aliens tend to move faster in alert state. Alert state is caused by the following:
- Spotting an enemy.
- Being in earshot of an Alarm.
- Being alerted by Scout Mook.
- Attack Dogs and hell-hounds also become alerted by hearing noises.
Fear
- This reaction is signified by a screaming sound and the enemy running away from the thing they Fear. Enemies react with Fear toward the following:
- All grenades/flares/flashbangs when they're about to detonate.
- MacBrover's basic dynamite (when not giving distracted reaction)
- All types of fire including B.A.'s flamethrower, Snake Broskin's molotovs and any fire caused by explosions.
- Bees from a bee hive.
- Proximity to Bro Dredd's missile, remote-controlled car or Xebro's chakram.
- Seeing the result of Brochete's, Brodator's or Ash Brolliams' melee attack.
- Broheart's or Ash Brolliams' special.
- Being hit with Indiana Brones' whip.
- Player under the influence of vitamins.
Terrorists can also gain fear status for:
- Being near various aliens.
Mechanical enemies are immune to fear except for the Super Mook.
Confusion
- This reaction is signified by spots around the enemy's head and has a duration of 8 seconds. Enemies may stand still for several seconds or move around aimlessly. When moving around the enemy may attack with a weapon in confusion if having one. When that weapon shoots regular bullets, they don't hurt Bros but damage mooks and various other enemies. Enemies with explosive weaponry can still damage the bros. Suicide-based enemies will go into suicide mode. Enemies react with Confusion to the following:
- Bro Hard's flash grenades.
- Bro in Black's neuralyzer.
- After dancing once Desperabro's special wears out.
Stun
- Stun, like confusion status, is signified by spots around the enemy's head. Stun usually lasts a short time. Stunned enemies stop firing momentarily and some stuns make them stop attacking altogether. Stun is caused by the following:
- Bronan the Brobarian's small shock wave.
- Ellen Ripbro's primary fire.
- Brolander's and Broden's lightning when it doesn't gib them.
- Mr. Anderbro's dash.
For face huggers, shooting its egg off the ceiling or wall causes the emerged face hugger to be stunned for a short time.
Distraction
- This reaction is marked by ? over their heads. Most distracted enemies will stop attacking. Dogs, hell-hounds and aliens become active and may move towards the player. Distraction is caused by the following:
- Noises such as door opening/shutting, explosions and firing weapons. Noises also make enemies turn towards the source of the noise.
- Sometimes when MacBrover's TNT is attached to them.
- Activating Double Bro Seven's disguise or Brodator's special.
- Crouching in Tall Grass.
Curiosity
- This reaction is signified by a question mark above the enemy's head. This causes most enemies to move toward the source of Curiosity. Mooks react with Curiosity toward MacBrover's Turkey Bomb, and Brodator's corpse. Aliens also react with curiosity to alien pheromones.
Flying suicidal enemies fall down and explode when gaining curiosity status.
Dance
- When the enemies start to dance, they abandon all their attacks. It can be achieved through Desperabro's passive and special.
