The voice commands are pretty good, actually. I was quite impressed, although I did occasionally tell team mates that I loved them... but that's another matter entirely
It's a relatively generic shooter, but it's been done quite well. It won't blow you away, but it's a solid title in my opinion. The shooting mechanics are pleasant, as previously mentioned the hit registration on the robots/dismantling them via bullets is very pleasing. However, the main aspect that impressed me above everything was where the story went. I'm sure some Sci-fi buffs will correct me, but the story takes a very unique twist in the last third or so, and I've honestly never heard nor seen any form of media that follows the same story path.
All in all, it's certainly worth picking up, but I'd never pay more than £15 for it. Worthy of your full attention, just not worthy of a full price.
