Death weapon is a pseudo-weapon that is triggered when a specific unit is destroyed. The few units that cause this kind of damage are described as volatile. These units are experimentals, mass fabricators and power generators.
It is worth noting that death weapons apply their full damage to all targets within their radius. By comparison, area of effect weapons like artillery are divided amongst all targets they hit. (Nukes also work like Death Weapons, the only exception to this is the Cybran Nuke. It can be defended against even if no SMD is available to stop it with Seraphim shields, which will absorb the shot and leave only outer ring damage undefended against.) In practice, this means that when your T2 mass fabricator dies, it doesn't divide the damage of its death weapon among the other T2 mass fabricators around it. Instead, it will destroy them all. Conversely, this also means that the suicide CZAR you sent against an enemy will do 10,000 damage to every single unit it land on, killing practically everything and bypassing shields, since the death weapon isn't triggered until the CZAR hits the ground, under your enemy's shields. Comparatively, a strategic missile may do a lot of damage, but if you have multiple T3 shields soaking it up, your hardiest T3 structures (and potentially even your ACU) can survive it because all that nuke damage is divided out amongst the targets. In effect, a death weapon can be a nightmare for you defensively, or a nightmare for your opponent if used creatively, and you should always remember this no matter which end of the bargain you find yourself on.
Colossus death[edit | edit source]
The Colossus death weapon is when a Galactic Colossus is killed in the field. It's a volatile unit, meaning it explodes on death.
It is a method of destroying enemies because of the death of the dying experimental. As they fall to the ground they crush anything beneath them doing tremendous damage. Most units will be instantly destroyed by this. This tactic is very inefficient and should only be used if you need to get rid of some Galactic Colossus's or you have tons of resources to spare!
The Sacred Assault Bot can also crush units (see massive) by walking over them and also does not require the death of a potential game-ender (and you can blast enemies too far away to step on with your laser)
