Wow... I can barely believe the gall of some people...
I guess its our job to clear the way. Head forward and jump over the missiles being shot at you (you *can* Blast these guys but it's a waste of sunstone). Head to the right (there's some relics by the clock) and then down the next hallway, which has more missile guys at the end (and more relics in the red vacuum).
In the next room you'll meet some new enemies. These small robots we shall call... chargers (making up names can be rough!). We'll call them that since they charge at you with a shield up. Just wait for the shield to drop and give them one good smack to take them down. Once they are dead the door will open and a new robot will come out. Let's call him a shock bot (good name, right?). He will float up in the air and then crash down, sending a shock all around him. After he does that you can quickly punch him out though.
Continue through the door and kill the shock bot. This hallway has more missile guards in it. Hang a right when you can and instead of going down the next hallway head right and hit the switch on the wall for...
HIDDEN CHEST #16:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
After defeating the second shock bot, take a right and head all the way to your right. You will see a switch on the wall. Hit it to unlock the nearby bars leading to this chest.
Head back and go down the next hallway, dodging missiles along the way. Be extra careful here: past the first arch is another missile guy in the distance that is easy to miss. Keep following the path and you'll soon fight another shock bot and a guard. The guard is very similar to previous weapon wielding enemies: watch out for swipes and dodge his overhead attacks. Once you beat them the door will open with another guard. Take him out and continue. You will soon see a scene.
Looks like we're headed up. Head out into the open room to take on a series of enemies. Nothing you haven't seen before, although you do get to fight a guard shooting missiles here (he is easy to take down, just watch out for the horizontal spread attack). Head up the stairs (go south if you need parts) and through the door.
You will see a scene soon. Afterwards, you need to run! Run, run! Don't stop for anything and you will make it in time (there is no need to stop: the robots break the sunstone for you).
Once outside gather the sunstone and head left. There's a mix of all enemies here, but take out the missiles first (be quick). Next up is a sword guard and a missile guard. The missiles are higher up so fight down by the base of the platform and you won't get hit. Take him out afterward and keep going to find two sword guards and a missile guard. This is a good place for a Shockwave attack if you can do it, otherwise take out the missiles and then the sword guards.
Head forward and you'll see a scene. The missile guy here is at the far end, so take care of the guard and then go get him. Past that are two more robots (one of each), and some relics on top of the steps if you need them. Continue on and in the next big area are two guards and a missile guy in the back. We once again recommend a Shockwave here but if you want to save take out the range first.
You may notice on the north wall (to the east) is a locked path to a chest. Not to worry: one the enemies are dead the west path will open. Go over there to find some relics and the switch:
HIDDEN CHEST #17:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
After defeating the second group of two sword guards and a missile launcher guard, go through the west door and hit the switch by the box of relics. Return to the previous room and go through the open door on the north wall for this chest.
Head back to the relic room and out onto the balcony to end this part of the chapter.
