Tenshi Doumei

Tenshi Doumei combines battlefield tactics and mech upgrades for an entertaining title. At face value, Tenshi is a tactical strategy RPG where you move units and attack or defend against cadres of adversaries.
Attacks consist of long range artillery attacks and close-range bouts where you invariably punch an enemy mech. The drawback of a punch is that the opponent will counter-attack within the close range. A long range fire attack will not prompt any return fire. Close range attacks are preferable in the first few levels because they inflict more damage.
