Not sure i really like this, but it's logicaly equivalent and cleans it up a little .. 
if( do{$o->check(...); ! $o->state} ){
   action..
}elsif( do{$o->check(...); ! $o->state} ){
     action....
     $o->blah()
     if ($o->state) {
        actions..check..
          unless($r->state) {
             and so on...deeper and deeper...
          }
     }
}

It's hard to say w/o knowing what the check() and state() methods do and their return values.. In general, I would say to push things off into methods .. 
$o->check(...);
unless ($o->state) {
   $o->actionSet1;
} else {
   $o->check(...);
   unless ($o->state) {
     $o->actionSet1;
   }
}

So what does the check() method return? if it did return $this->state then things simplify alot: 
unless ( $o->check(...) ) {
   action..
} else {
   unless ( $o->check(...) ) {
     action....
     $o->blah()
     if ($o->state) {
        actions..
          unless( $o->check(...) ) {
             and so on...deeper and deeper...
          }
     }
   }
}
