ok , so a while back i got a game space invaders extreme . its the 20 or 30th anniversary edition . its for psp and ds and of course i got the psp version . it has good graphics and it entertaining . it plays this music in the background and when you do stuff it makes a sound effect (like shooting) that kinda sounds like it should be in the song haha :laugh: and its a fun game . in classic space invaders you had the little shields (remember , the 3 of them) but not on this . sadly there aint no shields . but there are powerups and bonus lvls and bosses . the powerups are a cool feature . like if you kill 4 of the same color , kill 4 reds in a row you shoot filreballs ... ok im not gonna say them all right now lol but its a fun game , always trying to beat your old highscore and playing till your hands get so sweaty that you cant hold your psp . its entertaining , i would say a 3.5/5 , i would DEFINETLY recomend it! great game!
