The PS Vita Review Network has gotten their hands on EDF 2017 Portable and have given their thoughts.
"If you’re a fan of B Movies or running around and blasting away giant monsters, then Earth Defense Force 2017 Portable is the game for you. It’s got fun combat, and a huge number of weapons to unlock across both characters as you play through the game. There are a few technical hiccups with crashing, but all in all, it’s a fun experience that any Toho or Classic Monster Movie fan will not want to miss."
Because blowing up UFO's never gets old.
Satisfying visual feedback, so many games have lost this principle and it's sad. Almost everything you do has an interesting and Satisfying reaction, making everything physics based is the key to that, watching everything fly, crumble, and react to your weapons, and slowly increasing you weapons capabilities to do so to an absurd degree, just keeps ramping up the satisfaction of how good it feels to play this game.
Games are great, they may not be the greatest visually, but man do they really push the hardware they’re on cpu wise
VGChartz's Adam Cartwright: "Thanks to the timing of the Vita’s release and its relative power compared to the home consoles at the time (PS3 & Xbox 360), it saw the benefit of a number of these late ports which have remained the ‘definitive’ versions to this day. It’s these games that I’m aiming to look at in this article – titles that are best on Vita by virtue of extra bells and whistles, tweaked controls, and content, or in some cases just a general feeling that Sony’s portable hardware is the most enjoyable way to play."
VGChartz's Adam Cartwright: "Thanks to some solid late-in-life Japanese support, and a sea of backwards-compatible games, the Vita’s library of third-person shooters is a lot better than it first appears, covering a variety of sub-genres from horror to stealth to tactical, all the while providing games that are a tonne of fun to play."
Missed so many games.
Also backwards compatibility differs from region to region.
Literally some stores like the NZ/Aus store will allow syphon Filter 1 and 3 but not 2 and the USA store is different again
I haven't done it in a while so unsure if it has changed, but you used to be able to download any PS1 or PSP game to a PS3 and then transfer it to the Vita and it just worked - regardless of whether it showed as something you could buy in store for, or download directly to, the Vita. It opened up a huge library of back-compat titles that way.
It's a nice portable game.. Kinda gets tough for me tho even on just hard.. Probably need to grind for better equipment xD
