my current setup on enclave default ( base regen only used )
1. plasma cannon were initial setup upgrading them is optional
2. build the middle route of pulse emitters and route that closes it off by wave 62
3. once the is done build the back line defense. ( needs to be done by 72 for boss that comes
4. close off top ond bottom lines and build the extra part of the third line. optional but recommended build a weave of wall blocks just before the opening. there is a line where most of the new enemies will come from ( this will cut that off)
5. upgrade the 14 pulse emitters in the middle line then close off the area at the top and change the wall blocks to pulse emitters.
6. at about wave 285, close off the inside top route. and open up the outside top and use that to juggle the lines till filled
update: ended it at 360 with 147916 point. an all time high for mode on mochi games.com. could have gone further but decided to end it and try same setup on ground only.
