    Only a few levels in, but there is an obvious unpolished feel. The graphics are mediocre with gameplay to match. The voiceovers are buggy and cutout halfway through sentences. I'm hoping it improves soon, but so far it has the feel of Untold Legends, right down to the rotating character in the stats window.

    Definitely not the all time greatest game, but if you've got the itch to kill aliens and level up RPG-style, this satisfies. Playing it now years after release maybe allows me to be more forgiving, but I disagree with people who say it's not fun. It is. The constant loot and upgrading is addicting and makes a for a great diversion from the usual stuff.

    Played for an hour, but it's clearly lacks fun.

    For fans of classic action-RPGs or multiplayer addicts Alien Syndrome would be a solid weekend rental or bargain bin purchase, but given the lack of polish throughout, the overall lackluster graphical presentation, and the $40 price tag we’ve got to put SEGA’s latest effort in the “just skip it” category. There are far better games available on PSP, and far more are on the way.
  2. A sense of murky monotony sucks most of the life out of this action RPG remake of Sega's classic arcade shooter.
  3. Between the PSP and Wii, the PSP is easily the superior. It offers the better controls and graphics, and just feels like a better game. It's a little harder to find three others to play with, so I guess that offsets it.
