The Day 4: Icarus

Icarus is (despite the number in its title) the third installment in the Korean-made series of horizontally scrolling sci-fi shoot-em-ups. Once again, Captain Lee and his friends must stop an army of mechanized creatures from destroying Earth. Power-ups either change the weapon’s properties or enhance the current weapon by extending the shot, adding three-way fire, etc. Picking a different weapon, however, reverts to its default weak form.
