It's a UFO Invasion! Our world is under attack and you are Star Command's only hope. The fate of our world depends on you!

Blast the UFOs in each of the six Space Sectors and scavenge their destroyed alien ships for ammo, shields, and weapon upgrades (collect the falling power-ups) in order to stay alive as long as you can. Be warned: each Wave of UFOs becomes more difficult to destroy!

Both kids & adults love playing Invasion, a 2.5D casual shooter game (not intended for hardcore gamers). Invasion is a perfect addition to your Windows Phone's Kids Corner!

INVASION GAME HISTORY:

The original 2002 Invasion game was written by Mauricio Ritter with DirectX 6 in C++ for Windows XP. It was ported to Managed DirectX in 2003 by Steve Maier. Windows Phone versions (2011 XNA, 2013 MonoGame) were ported by Dan Colasanti of ImproviSoft LLC. Source code for all versions can be found at www.codeproject.com!

THE FUTURE:

ImproviSoft intends to keep "Invasion for Windows Phone" free and open-source! We plan to make improvements to Invasion in upcoming releases. If you are a graphics designer or app developer and would like to contribute your time to this project, please contact us at Support@ImproviSoft.com.
