A basic model Constructo Bomb

The Constructo Bomb is a metallic glove which holds the bomb on its palm. Its appearance will change depending on which components of the Constructo Bomb are equipped as it is used.


The Constructo Bomb is a versatile weapon that can be useful against various sorts of enemies, depending on how the player chooses to customize it. Its trigger, payload and additional upgrade can each be customized.

The basic Contact Trigger causes the bombs to explode on contact, and adds no major effect to the weapon. The Proximity Trigger causes the bombs to only explode when an enemy wanders within its range, allowing it to work as a mine. The Timed Trigger adds a three-second delay to each bomb after landing before it explodes, allowing for a further bounce. Both the Proximity and Timed Trigger fundamentally change the purpose of the weapon strategically, but there is no major disadvantage to leaving the basic Contact Trigger equipped.

The Explosive Payload is causes the bombs to deliver a basic explosion on detonation. The Shockwave Payload generates sonic shockwaves with each explosion, maximising its radius over raw power. The Skyburst Payload allows the bombs to explode vertically, allowing them to easily target airborne units. The Skyburst Payload is a situational mod that can be very effective against enemies in the sky, but the player should equip the other mods when fighting most enemies.

The Toxic Upgrade adds a damage over time toxin to the bomb after it explodes. Due to its blast radius, it can apply the effect to multiple enemies and deal decent damage. The Shrapnel Upgrade causes the bombs to hit nearby enemies with shrapnel shards, increasing its area of effect to damage more enemies. The Barrage Upgrade causes the bomb to deploy a cluster of minibombs which can ricochet around and either damage more opponents, or hit the same larger opponent more than once. Each of these upgrades provides completely different effects, and it is down to player preference as to which they should equip. The direction of each of these additional effects is determined by the bomb's payload.

Before the scene

If the player wears a skin while having the Constructo Bomb equipped, it only shows the bomb but not the glove.
