OK so I played through what I assume is the tutorial- various missions leading up to a boss (Vor?). I read quite a bit about this game and it sounds great, the Warframe skills in particular sound really interesting. However, the few hours I spent playing consisted of me walking towards objective markers mashing the melee button and winning. I used my abilities a bit but they didn't seem necessary and I wasn't finding much energy. Even the boss I just walked up to and mashed the attack button.
I haven't been able to unlock any new equipment and didn't realize I'd be stuck with the weapons I chose in the tutorial bit for hours, or with the Warframe I started with (Mag).
That's all very negative, but I don't want to say I don't like the game because there is so much I don't understand. Does my account sound normal for the tutorial bit? Am I missing something? Does the difficulty go up so that you have to use your abilities intelligently? How long is it likely to be before I unlock new stuff? I did unlock two new Warframe powers but didn't realize I had them for quite a bit.
