The different types of OIES have different amounts of hit points and armor values. Offensive Modules Offensive Modules are used to attack other bases from the player's base. In order to work, the player must have an attack marker, which will tell the Offensive Module where to fire, along with a certain amount of minerals. The attack marker can be aimed using the zoom in and zoom out functions. The player must also keep the attack marker on the target until the weapon hits.
Mortars are the most powerful, but take a long time to fire and are quite inaccurate.
A Guided Missile is quick to launch and accurate, but does the least damage. The other weapons' launch times are somewhere inbetween the Mortar and Guided Missile. Napalms set fire to structures and do damage over time, along with the initial explosion damage. Splitting Bombs split into many explosives in the air, showering the enemy with a large amount of explosives. A Bombing Run launches planes that drop bombs in a line from the player's base to the end of the map in the direction of the attack marker.
