Out Zone

Out Zone is a 2D top-down shooter. In the year 2097, mankind has a big
problem – it’s invaded by an alien race. The player is a cyborg soldier who
must fight against aliens enemies – and destroy the invasion force.

The game is a shooter similar to Commando – the player advances on the
vertical scrolling playfield and shoots the enemies. He has two weapons: the
semi-automatic forward gun and an all-direction laser (with rapid fire). It’s
possible to collect special bonuses. There are seven levels, at the end of
each level, a boss awaits.
