This Time, It's War On Your Mobile Device!
You play as both titular species in a campaign that bounces back and forth between each ones story line. Both are fun and feel balanced in the sense that neither feels significantly more fun than the other and you also don't spend lopsided amounts of time in either campaign. Granted, there are some difficult sections in parts of the game so it's not a total 'walk in the park', but on a normal setting it provides enough of a challenge and at about the right pace. Plus, in addition to the main campaign, most chapters also have their own side mission which all range in task from increasing horde modes, to kill the enemies with ___ skill / weapon missions, etc. And beyond that there are 2 additional 'secret' levels that can be unlocked by finding secret items (one's a legit 'level', the other's an arcade style game based on another popular mobile game) throughout the campaign. Throw in a trophy system and last but certainly not least the ability to upgrade your alien or predator with different weapons and abilities and you have a game that offers a good variety of things to do and the potential for a lot of time spent having fun doing it.
Even though the game has a lot to offer, it isn't without its' flaws. Chief among them are the somewhat wonky controls and crowded buttons. Mobile touchscreen devices haven't quite mastered the dual stick controls on their devices yet and that's a large part of the problem. The other is that all the buttons tend to get crowded together. But again, that's just part of dealing with the small screen size. I played this on a Motorola Android phone, so I didn't experience the larger iPad scale and that might solve some of the problem. Regardless there were one or two sections that felt like they could have benefitted from a little better control. And that was my biggest and most significant gripe. There were other nit-picky type things too, like the fact that the predator can't really jump vertically; just lunge forward really fast. And yes, the alien has some wall control issues, as it seems to with all Aliens games.
But overall this game is pretty solid. It's got fairly good graphics, decent sound, authentic sound effects, it offers a pretty decent amount of content and at $4.99 it's very inexpensive and certainly a reasonable price. Again, this is all with the fact in mind 'it's for a mobile touchscreen device'. I certainly enjoyed this game and definitely recommend it to fans of the aliens and predator series, as well as sci-fi / action-adventure fans too. And I kept wanting to rate this game an 8 on a 10 scale, but there's just something about it that keeps holding me back. I'm waffling on it for sure, but in the end, I'm going to go with a 7.5 and split the difference.
