    [[
	You are stranded on this coastal planet and your mission is to get out of here.

	The peaceful inhabitants live in the sea and are plagued by bugs.
	They need your help!

	They will send you the bugs along with the seabed to the surface.
	If you eliminate the bugs, you will receive credits as a thank-you for removing the bugs.
	With the credits you can buy raw materials from requirement boxes.
	These can already be found on the coast.

	Be careful! Over time, residents will send stronger bugs to the surface!

	Turrets unfortunately malfunction in this world.

	Any container bearing dangerous goods, like ammo, grenades or barrels,
	causes heavy explosions when it breaks.
	Maybe this can be used to our advantage.

	--Good Luck Troopers--
