Quoted from SolarRide:complete level 3 of a mode and a particular shot is doubled.Klingon level 3 causes left ramp to be doubled.
Save the enterprise 3 and right ramp is doubled. Nero 3 and left orbit is doubled, Space jump 3 and right orbit is doubled. On v1.5, the doublers stay for the whole game. Warp 9.1 and 9.9 create double scoring for all features not just loops,saucer and ramps, but only for 40 seconds and these can combine for 4x scoring with L3 or combo doublers. combo shots create hurry-up doublers on a ramp,orbit or the saucer, but they don't combine with L3 doublers.
Shhhh! I have to play ST against RD on saturday .
