Sky Force Anniversary

Sky Force is a vertically scrolling shoot 'em up video game series created by the Polish video game developer Infinite Dreams Inc. The gameplay is reminiscent of Capcom's 19XX series and Seibu Kaihatsu's Raiden series, featuring a weapon upgrade system and large end of stage bosses.

The original Sky Force and Sky Force 2014 has the player fighting the evil General Mantis, who seeks to rain havoc upon the world in his Night Owl. The player must defeat his various ships, planes, helicopters and tanks, with his final battle failing as his Night Owl gets destroyed and falls down to the ground. In Sky Force 2014, after you defeat General Mantis is another stage where you face an AI controlled robot called Omega in his mech. But even after destroying his mech he survives.
