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 the hearing radius of Alarm.

Fear

This reaction is signified by a screaming sound and the enemy running away from the source of Fear. Enemies react with Fear toward the following:

• All grenades when they're about to blow.
• 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 of Bro Dredd's missile.
• Seeing a result of Brochete's Brotator's and Ash Brolliams' melee attack.
• Broheart's and Ash Brolliams' special.
• Getting hit with Indiana Brones' whip.

Terrorists can also get fear status for:

• Being near various aliens.

Mechanical enemies are immune to fear.

Confusion

This reaction is signified by spots around the enemy's head and has a duration of 8 seconds. Enemy 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 not hurt Bros but damage opponents. 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.

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 shockwave.
• Ellen Ripbro's primary fire.
• Mr. Anderbro's dash.

For facehuggers, shooting its egg off the ceiling or wall causes the emerged facehugger to be stunned for a short time.

Distraction

This reaction is marked by ? over their heads. Enemies with distraction will stop attacking. Distraction is caused by the following:

• Noises such as door opening/shutting, explosions and firing weapons.
• Sometimes when MacBrover's TNT is attached to them.
• Activating Double Bro Seven's disguise or Brodator's special.

Curiosity

This reaction is signified by a question mark above the mook's head and the mook moving toward the source of Curiosity. Mooks react with Curiosity toward MacBrover's Turkey Bomb.
