SWiV

SWIV is a vertically scrolling shoot-em-up which plays in a typical fashion to other games in its genre. The player chooses between using either a helicopter or a jeep at the beginning of the game and then plays in their chosen vehicles through scrolling levels, shooting at oncoming enemies. Certain enemies when shot drop shield power-ups which can be either picked up to afford temporarily invincibility or detonated to destroy all enemies onscreen. Every so often a boss enemy will attack. The destruction of these bosses will give upgrades to the player’s forward firing gun.
