Battle stream and waterpool is a pretty epic combo for features since you end up with your full multiplier for overdrive (potentially more if you upgrade waterpool further) on all weapons giving a decent damage multiplier to idling, much better combo than the one that increases auto weapons whenever overdrive is empty (and you dont need too many ranks in battle stream to make it keep overdrive constantly full)
this is a nice time waster/killer though i'm gonna be sad if unity doesnt change their platform to support the changes in chrome when they eventually remove the advanced setting to make unity still work
there is working version in chrome now
