This is a relatively tough future level. Make good use of your bazooka here, killing anything you can from far away. The robots can't be bazookaed, but they always shoot left-right-left (or right-left-right) before turning their vunerable side up. Just shoot or spin him then.

The first batch of 4 invisible blocks can be activated by shooting the bazooka far ahead, right in the center. The next batch you hit will have two activators - one on either side of you. The rest of the level is relatively straightforward. When you get to the bonus section here, it's almost all bazooka work.
