Classic Game Room HD reviews STAR DEFENDER 4 published by Alawar Games, available as a reasonably priced download for PC. This Galaxian-meets-SHMUP space shooter should appeal to fans of 1980's arcade games like Galaga and Space Invaders as well as the modern crop of bullet hell style Japanese space ship shooters. Blast waves of aliens into bits with a variety of weapons and power ups while dodging asteroids and gunfire. This CGR review of Star Defender 4 has gameplay from the PC version of Star Defender 4 showing arcade style game play in HD action. Get some alien wrecking power as you level up your primary weapon and fire away with the left mouse button, catch falling power ups like guided missiles, lasers and flame throwers. Oh yeah, Star Defender 4 real baby!
