Weapons Bed is the seventh Dark Story stage and one of Dr. Eggman's shooting stages in Sonic Adventure 2. As part of the diabolical scheme to rule the world, Dr. Eggman is going to cause a distraction so Rouge can grab the Chaos Emeralds from Prison Island.
Dr. Eggman must run around the Carrier fleet that belongs to G.U.N., and destroy all the robots he finds, and cause as much havoc as possible as part of a planned three pronged assault to steal three Chaos Emeralds (as discussed in the cut-scene). Despite this being a shooting level, it bears a striking resemblance to Sonic's Metal Harbor level, due to the fact that both take place very close to each other (geographically and chronologically). Eggman's role in this particular mission is distracting, gaining the attention of the security forces of the military, to allow his accomplice Rouge the Bat to steal the Emeralds from the large security vault located within the G.U.N. compound undetected. As seen in some previous missions, bomber jets will swoop down and drop bombs in your direction periodically. There are many GUN Hunters here, but they are dormant. Players should be careful of the Hawk G.U.N. series, as many will attempt to ambush or strike when least expected.
Collect 100 rings
As usual, collecting a hundred rings would be easy if it were not for the G.U.N. robots around who keep bothering the player. The Weapons Bed stage is murderous when it comes to hanging onto rings. The robots pop up out of nowhere and fire streams of shots at the player. Knowing when they’ll show up will help tremendously. Also, tap the player fire button instead of holding on and waiting for multiple target locks. This makes it easier to blast enemy shots out of the sky.
Find the lost Chao
On the third aircraft carrier, look in the last garage to the left, and play the Mystic Melody near the ancient shrine in there to make a blue swirl appear. Jump in, and the player is transported to a platform where the lost Chao is tucked between some metal boxes.
Reach the goal within 2:45
Completing this mission is easy as long as the player resists the temptation to stop and destroy all those helpless, stationary enemies. Do continually fire as the player walks, however, to smash any iron containers in the way.
Clear Hard Mode
In addition to some more aggressive enemies, this mission contains a couple of minor path changes. The first involves crossing a gap, where the opposite side is closed with unbreakable containers standing on the Iron ones. Rolling spiked balls also added to it.
The first Chao box is in a small nook just past the garages on the first aircraft carrier.
The second one is hidden next to the cylindrical fuel tanks on the right-hand side of the second aircraft carrier.
At the end of the third aircraft carrier, the final chao box is right next to the cylindrical fuel tank in the right-hand corner.
