If you liked the original Anomaly (Which I loved), chances are you'll enjoy this. It bares no real differences besides the fact that this is a ♥♥♥♥♥♥ mobile port where alt-tabbing will lead to certain doom. If you've never played the original Anomaly I'd suggest skipping this, but if you're adamant, let me tell you what you have in store for you.
This is a "tower-offense" game, the inverse of the usual tower defense. It's a short game, but there is a splendid variety of units for you to bring into battle, and towers for the enemy to set up. You will take on several story-based missions that serve as kind of a sequel to the original Anomaly (So if you've never played that, you'll have no idea what's going on here). The game challenges you in different ways such as preventing you from calling in more units, stopping you from acquiring more powerups (Very important tools you can use to give your units the edge in battle.), giving you a time limit, and etc.
The story isn't as in-depth (Nor is it necessary to experience before moving on to Anomaly 2), about every unit is recycled from the original, there are NO graphics options to speak of, nor any audio quality options.
It's a very unique concept but also much better done in the original Anomaly game rather than this crappy mobile port. It's ok, but really not a must-play unless you're head over heels in love with this series. I'll give this a 6/10. It's ok, it's not bad, but doesn't really live up to the name the original Anomaly made for itself. This PC port was clearly just made as a grab for money as the port itself has no effort put into it, and because of that, I cannot recommend you picking this up on PC.
