Crystal Palace East (map name: rcboss1)

Don't be surprised by the guy in the elevator when it opens. Kill him, ride up the elevator and get ready for boss number one. He's tough, but he'll go down with about 10 rocket hits (or 34 or so crowbar whacks!) Once you finish him off, go back and ride the other (left) elevator up and on to the next level.
