Infused Originium Slugs Will Move

The Infused Originium Slugs that populate the map during the start of the operation will not move initially. The Slugs located near the entrance of your base will move to the right, requiring no need to immediately dispatch them.

Eliminate Slugs As Fast As You Can

It is important to destroy all of the Infused Originium Slugs as early as you can. Use ranged units such as Snipers and AoE Casters to deal with them. Use other Operators to stop them from advancing should they start to move.

1. Destroy Top Slugs First
