An endurance test of killing aliens
Almost everything about this game is great. The quality of the graphics, the variety of weapons and that they actually act differently, the intelligence displayed by the aliens. The most amazing thing for me was the quality of the cutscenes. I've seen major movies with lower production values.
The singular downside that I have with the game is the fact that fairly early on you achieve the peak of weaponry. Given this isn't a problem solving game, it rapidly turns into a endurance match of blasting aliens. And while that is fun, after a while it stopped being fun and became a task, which is pretty much counter to the whole point of playing a game.
Don't get me wrong, I can see how that can be fun. It's just where I am right now in life took the fun away for me. Maybe if I had a worse boss...
