Power Factor is basically a side-scrolling Xybots. You go around shooting stuff, much like Abadox, only you're a guy and it's not forced-scrolling, and it's in a building. Normally, I would say a game like this is a meh, at best, but what saves this game from it is the codes. I can't play games very good (which is why I like puzzle games), so when a game comes along with an invincibility code, especially for the Lynx, I get it. Without it, I can only go as far as level 2 (Yes, I can beat level 1, which is more than I can say for Toki). But huzzah to the game programmers to put in the invincibility code, which allowed me to get to level 6 and played for 1/2 hour before I got bored and turned the Lynx off. There's also a stage select code and a power-up weapons code. So, I give this game a , especially if you like games where you go around shooting stuff.
