About This Game
Command knights, aliens, and other historically dubious nations in a free real-time tower conquest game rebuilt from a 2009 iPad original. Grow armies, capture towers, and outmaneuver adaptive AI through 30 campaign levels.
Detailed Description
You are a commander tasked with defending Medieval Europe against a fearsome Alien Invasion, which historians agree definitely happened. Gesture vigorously to your elite, knight forces to command them into battle. You are the only commander brave enough to save the world by dragging tiny armies between towers with the urgency of someone who has just spilled coffee on a battle plan. Fail, and Earth may experience a brief administrative change in ownership.
CONTROL your troops with potentially VIGOROUS gestures
DEFEND EARTH as one of five ANGRY European nations
NOT HAPPY with FIVE? Unlock USA, the secret TIME TRAVELING nation
KICK ALIEN BOOTY on THIRTY maps and THREE difficulty modes
OUTMANEUVER dynamic AI that notices when you are doing too well and becomes PROFESSIONALLY UPSET.
MIND CONTROL one EVIL Alien nation and CONQUER earth yourself
REACT FEARLESSLY to fog of war, darkness, and sunset battles, three conditions famously solved by PANIC.
LEVEL UP YOUR MIND with EXTREME historical accuracy (historical accuracy not included)
EMBRACE the KNIGHT CODE: KILL ANYTHING GREEN!
Also: BEARS.
DON'T LET THE WORLD GET EATEN
Knights vs Aliens is a free classic re-release of a small strategy game originally shipped to iPad in 2009 under Prophetic Sky. This version has been rebuilt in Godot for Steam, desktop, and web, then returned to public life because it is still weird and still fun.
CAUTION:
This intense historical experience may cause your FINGER to BREAK OFF and/or MELT. You may want to consult your NEXT OF KIN before use.
REQUIREMENTS:
KvA was designed to work with items found in your home. We don't actually know where you live, but I assume your computer will play it - if your computer can't compete with a 2009 era iPad, you should probably upgrade.
