Effective against armor, shields, and biotic barriers. 'Rapid-fire missile launcher with seeking projectiles. Very effective against armor, shields, and barriers.' Inflicts high damage with a large area of effect. Thought a technically inaccurate label, this prototype weapon is nicknamed the 'Nuke Launcher,' and its high-explosive matrix generates an archetypical mushroom cloud on impact. When accelerated to 5 km/s, the round is devastating. Normandy's scientists have prototyped a modified version of traditional high-explosive rounds that is applied to a 25-gram slug. 'The effectiveness and efficiency of mass-effect-based weapon technology has rendered large-scale deployment of highly explosive weaponry all but obsolete in infantry weapons. Normandy's scientists have found a way to apply this technology on a large scale by generating a mass effect containment 'bubble,' this proof-of-concept large weapon technology is effective against armor, shields, and biotic barriers. A cooling laser collapses the ammunition into Bose-Einstein condensate, a mass of super-cooled subatomic particles capable of snap-freezing impacted objects. 'Cryo Round technology is used to modify standard weapon slugs.

Modifying the gene sequence of the virus and injecting a small amount into a krogan can introduce a change in that genetic code.'

A scientist named Okeer designed a retrovirus that matches the krogan genetic code. 'All krogan squad members get +25% health.
