Mortars

Mortar description
The mortar is one of the 3 tier 2 upgrades for the rocket tower. The other two being the medium rocket launcher, and the S.A.M(surface to air missle). The mortar does heavy damage within a small area of the field. Because of this, slow towers work very well with the mortar. The slow will group enemies up, allowing the mortar to dessemate basic/fast ground troops. The disadvatage of this tower, is that it is very slow, thus why the slow tower works well with the mortar. The next upgrade is the artillery. it has the same rate of fire, a much longer range, and very heavy damage.
