Played a couple of hours of Mars with GhostBear.
...wasn't enjoying it.
The weapons are kind of cool (and some are now available in Montana- one of the pistols is a rocket launcher and is AWESOME). Mars itself looks gorgeous- I half-expect to turn around and see Matt Damon waving at me. Very nostalgic of Red Faction: Guerilla while playing this. (I guess that just got remastered, might give it a look sometime). The creatures- oh those are some of the best-looking critters a game has put out in a long, long time, very unique and fun. A lot of work went into creating them, clearly.
That environment is completely let down by the game play.
The shift from Hours of Darkness is shocking- yeah, it's Mars, there's no jungle to be sneaking around in, but there's no stealth play here at all- which is tough to adjust to at first. The entirety of the game is climbing towers to get power cores- back to Ubisoft doing what they love, fine. The first couple of them are kind of fun, but it gets old very quickly- and there's a LOT of them, looking at the map and horizon. The creatures are fun looking but very one-dimensional, and killing one doesn't really do much for you except earn you a couple of space-bucks- more will spawn, great if you're grinding for cash but not particularly rewarding otherwise.
I'll finish this one off, but as with Hours of Darkness I don't see myself ever wanting to go back to this one afterwards... the zombie one had better be really something to justify that season pass, at this point. At least Far Cry 3 has been fun to go back to...?
