YO this game was actually a super fun beat 'em up/brawler, the presentation was great and they put a lot of effort into it, my main complaint is difficulty as even on Level 2 there's enemies that will fuck you up if you're not prepared but I did really enjoy this one a lot, all the different aliens are super fun to play as and it's just a fun button masher!
I LOVE THIS GAME! One of the most fun beat 'em ups I ever played! Always wished we had all 10 aliens since I saw this as a kid but oh well, the fan game Hero Time is getting there. Being a Ben 10 fan of course makes this game better for me. As for the game, it feels amazing to play, very and the aliens are beautiful utilized and the graphics are spot on. I played this on PSP simply cuz it was easier to emulate for me then, as far as I can tell only true loss from that is that they removed the overworld voices, such as Ben quipping or Grandpa Max reacting when you keep hitting the RV, "Ooh good job hero! Very good, Ben!" lol, atleast I got to hear those when I tried the PS2 version some years before this. Aside that this is a great port, I can't advise the Wii version much, atleast emulation wise but PCSX2 should be a better option these days. It also baffles me how the Ben 10 games after this tried to copy this one exactly yet failed in getting how good this one felt, especiall Ben 10: Alien Force.
