Mister Viking

Mister Viking is a Viking-themed vertically-scrolling shoot ’em up game
where you take control of a Viking searching for the lost treasure of his
people.

As the character makes progress he has to fight of creatures who walk or fly
in the screen from all directions. The player has the ability to shoot in all
directions to fend them off. To aid the player a bit a Viking ship
occasionally appears to drop special weapons like bombs and swords that can be
thrown at the enemies. Some buildings also yield these special weapons when
destroyed. The game can be played solo or with a friend in alternating turns.
