I don't really like the prospect of endless shooters, especially when there's a story involved, since it gives you a goal you can never really reach. The gameplay's a bit monotone compared to your newer games too, with no power-ups, or bosses, or progressive difficulty, it just goes on and on and on, and until you choose to or get lazy it's pretty much impossible to die. The largest medals however, are at a risk of taking so long to gain the API connection times out before you reach them, in which case I suppose they won't unlock, which is a shame if you spend that much time getting there. As for the secrets, not sure when you get them? Seems there's a pattern there? Based on distance... maybe? Anyway, it's a good shooter, but could use some work. Keep it going!
