Having just recently finished Armed with Wings 3, this game feels somewhat short and lackluster. Of course, if I hadn't just recently finished Armed with Wings 3, I would probably be saying it's a really great game, therefore it's a really great game.
It was nice until the end, where the game completely left me behind, and I couldn't understand what it was trying to get at. As a game, not too hard, nor is it too easy, and really makes you think during some parts.
There aren't any pistols in this game right? That's realistic actually. In real life, switching to a different weapon isn't faster than reloading, and the weight the pistol and its ammo take up could be used for more ammo for your main gun instead.
