I liked the way the tanks and drones were used. They are not really a threat except in large numbers. But shooting them to get ammo, and having to clear them out to make sure your missiles don't accidentally lock onto them makes shooting them useful. I wonder if we'll have a few levels where we have to go on foot inside a building or something. That would be fun.
True, I just hope there's more variety which I'm sure there will be. I do like the cycle of combat. Getting out of the mech is interesting, I also hope there's some on foot missions. Everything kills you so fast when you're on foot though, perhaps that changes with upgrades etc. which will lend more credence to the idea of on foot missions. I really want to see where this game goes from here on out.
