Base Defender: Urban Siege is an intense base defense shooter. You are the last line of defense for a strategic base, in the heart of a city under alien invasion. Waves of enemies pour in from the skies and the streets — from hostile creatures to the most advanced spacecraft.
You're alone. But your cannon is ready.

Survive wave after wave
Face relentless hordes with an evolving arsenal: machine guns, heavy shells, homing missiles, flamethrowers, miniguns and more. Every weapon is a chance to survive a little longer. The further you go, the higher the pressure — hold your ground, boost your firepower, adapt your strategy and become a legend.

A true alien shooter, anytime, anywhere
Base Defender is an offline shooting game: no wifi, no internet needed. Stop the alien invasion on the bus, on a plane or on the couch. It's the perfect base defense game and survival shooter for quick sessions and long battles alike.

Easy to pick up, hard to put down
Simple one-hand controls and a built-in left-handed mode make it easy for everyone to jump in. A wide variety of enemies, bosses and spacecraft keeps every run fresh, while your upgradeable cannon makes you feel more powerful with each wave.
