The so-called Death Weapon is the explosion created by bigger or volatile units on death. Most experimental units tend to have this feature, as well as some buildings including Energy Generators and nuclear missile launchers. This explosion damages friendly units, so it is advised to keep units with a Death Weapon apart from other units. In particular, it is not recommended to build tight clusters of energy generators. Clusters of energy generators can be easily destroyed, as each power generator is destroyed it will damage its neighbors, making it easy to destroy them all.
