The player’s space shuttl es consist of thre e
types. In accordance with the different
weapon equipm ents, there are three kinds
of laser beams (
α, β, γ). Τ he energy propor-
tion is 1:2:4. Enemy’s space shuttles are also
equipped with
α, β, γ laser beams. Their
energy proportion is 1:2:4. For example, destroying the enem y’s sp ace sh uttl e “ ”
needs to fire either
β once or α twice, while γ
could penetrate it. Energy contrast table is
shown as follows:
