Morale

Morale is a mechanic that rewards a more effective team with greater ground presence. It is represented by a bar at the top of the screen.

Morale changes with the destruction of aircraft or creeps. Destroying an aircraft increases your side's morale by 1.25 while destroying a vehicle increases it by 0.5. As such, destroying a wave of 4 or 6 creeps has a greater impact on morale than shooting down 1 or 2 aircraft. Morale increases the rate at which waves of creeps will spawn on your side. This, in combination with the kills required to achieve greater morale, can create a snowballing effect. '
