The seeders in the game interrupt radio frequencies which make it hard on the COG to communicate with other members of the team. The only way to destroy the Seeders is to use the Hammer of Dawn during an open sky and when the hammer is online. and in Gears of War 2 the seeders can be killed by a brumak. The Seeders make their first appearance in Act I and also appear in Act IV. For offense, the Seeders spit out Nemacysts, which are flying creatures that explode on contact with an enemy. Each seeders have two mouths, one on each side of the face, one of the mouth can be considered as its anus. If there is a battle going on, the seeders dont move at all, all they do is shoot out Nemacysts. The first time we meet the seeders is in the hammer chapter of act 1. They only appear in acts 1 and 4 In gears of war. But in Gears of War 2 they appear in Acts 1,2,3 and 5.
