The Two-Step Goodbye is a unique variant of the ballistic fist, with only a single barrel mounted on the forearm. Sections of this ballistic fist are colored yellow, as opposed to the standard variant's monotone color scheme. An explosives warning symbol is printed on the side.
If a target is killed by a critical hit, the contact-triggered explosives will detonate within the fallen target after two seconds, subsequently dealing an extra 175 splash damage. Friendly non-player characters caught in the blast radius may become damaged, and even turn hostile, if the user isn't careful.
Enemies hit by or killed with this weapon fly a few feet back before exploding. This is useful for sneak attack criticals because it allows the player to determine where the enemy's body might fly before detonating.
Both the main attack and the secondary explosion can achieve stealth kills.
There is a beeping noise, similar to that of frag mines, that warns the player about the secondary explosion before detonation.
Due to the weapon's secondary explosion, the player should be careful using the weapon in close proximity to friendly non-player characters. For example, if the player is attacking a Freeside thug while a member of the Kings is attacking as well, the secondary explosion may kill the Kings gang member, causing a loss of reputation in Freeside.
This weapon uses the intended Pip-Boy 3000 icon, instead of the power fist icon previously used for the ballistic fist.
Despite its low critical damage, its x4 critical multiplier is its largest trait, a maxed critical chance character will have up to 117% chance to critically hit, the highest critical chance for any Unarmed weapon, therefore they will continue to get critical hits and trigger the detonation every time the enemy is killed.
If an enemy is killed by a critical hit in V.A.T.S., the player may not be able to escape the blast (there is a delay between killing the enemy and resuming control) which may cause minor health loss, crippled limbs (especially legs) or in some cases, killing the player.
