triple damage/triple armor/triple speed supplies that don't last as long as the regular ones. maybe a double score one, 1 flag = 2 flags, points are captured twice as fast, 1 kill = 2 kills in tdm and dm

freeze m1 m2 m3 could have a stronger freezing effect cause firebird and isida effects increase as you buy modifications.

imo there should be an ideas for modules thread Maybe an explosive module where a tank does damage upon death. Or a score module that increases a player's exp while playing. Or a jetpack module that allows tanks to fly for a short period of time.
