Mustard gas

The mustard gas capsule, after landing on the battlefield, expands into a large cloud of gas which lingers on the battlefield for a long period, damaging all units that pass through it. It spreads somewhat unpredictably from the impact point, making it difficult to use against large groups of enemy troops, and it is also dangerous to use on the front lines, since if your units defeat the enemy they may very well move into the cloud themselves. It is very effective against units like liquidators, since those tend to stay stationary and are far away. Like most other supports, the landing of the shell itself also does some damage to units in the vicinity.

Once the "Mustard gas" technology (level 6 genetics) is researched, they can be constructed and upgraded at your artillery factory. The upgrades cost both Genetics research points and resonators.

Note: The description for upgrades often does not match the actual effect of the upgrade. The values shown in the table below are the actual benefits of the upgrade.
