## Description
_Monadius_ is a freeware, open-source space shooter with vector graphics,
created as a homage to the Gradius series of side-scrolling games. As in those
earlier titles, the player controls a spaceship crossing the screen and
shooting down alien forces, while penetrating cave-like structures and
carefully avoiding collision with obstacles and the many projectiles from the
enemy guns. One of the hallmarks of the series is the menu-based power-up
system: some of the destroyed aliens drop energy capsules, that can be
collected to move the selection highlight from the menu at the bottom to the
desired power-up. There are various types of power-ups available: speed
boosts, missiles, satellite guns that surround the ship, double shots, laser
weapons and other similar upgrades. Some of them can accumulate, with the menu
entry getting crossed out when reaching the maximum allowed. All the levels
end with a boss fight, where a large foe has to be defeated by quickly
learning its movement and shooting patterns.
