You know this game is fun, even if you haven't played it yet, you know it is fast-paced, violent and light in plot. So just let me tell you a few things that surprise me, for better or for worst
First, the fact that full screen blocks you to that window (Unless you trick the program) is BS and makes the option of borderless completely useless. The fact that you can't skip logos at the start is annoying. And the position of the terminal button can make you press it in the heat of the battle (Which is a problem).
Second, for a game so focus in violence, it is really fun to explore for secrets, specially because the map always tell you where the things are, just not how to get them. The only problem are some levels that block back tracking without warning.
And finally, I'm surprised that I haven't heard as much praise for the progression, because it is excellent, in every level you feel like you are discovering, unlocking or trying something new, that being weapons, weapon mods, runes, powers, enemies, bosses, etc. There's always something exciting to do, and no every game can say that, so I think that deserved a bit more love.
A great game and a must-play if you like shooters
