Aggressive fungus creatures that eagerly engage in melee combat.
Rotshrooms are very dangerous enemies that appear only in Fungal Forest. They have fairly high health and always come in large groups, necessitating the use of high-levelled artillery towers. Rotshrooms do not deal much damage with their regular attacks, but when they die, they release a spore cloud that infects all nearby soldiers, dealing fair damage over time.
- The 500mm Big Bertha is particularly useful against Rotshrooms: Cluster Launcher Xtreme can halve the health of a whole group, while the regular attack is also effective against the Rotshrooms' large numbers.
