	The biters have caught the scent of fish in the market.
	Fend them off as long as possible!
	This however will not be an easy task,
	since their strength and resistance increases constantly over time.

	Your ultimate goal is to evacuate all the fish to cat planet!
	Put them in your rocket's cargo and launch them into space.
	Don't worry, you will still get space science.

	The Market will gladly take any coin you might find.
	Additional turret slots can be bought at the market.
	Several unique upgrades are available too.

	Researching tanks will unlock the artillery technology early.

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