Fire Weapon Explanation:

The Fire Weapon command seems to fade in and out of popularity, depending on the tactics used byother cybugs. At the moment it is fairly popular again, mainly because people are using cloaking which drains their ammo reserves, so by using 'fire weapon' correctly they can reduce the amount of ammo that is required to kill an enemy. 

The command fires a weapon up to 5 spaces in front of a cybug. The amount of damage that it does varies according to whether the enemy is shielded or unshielded, and how far away it is. For example, these are the default values:
 

 
Spaces
With Shield
Without Shield
1
2
5

4

In order to use Fire Weapon effectively, a cybug has to work out whether the enemy is shielded and how far away it is. This can prove quite difficult!!
