I don’t think I would call HD2 an extraction shooter. I mean sure, you shoot things and try to extract, but for the same reason HD2 isn’t a RPG just because you can roleplay or an RTS just because you need to make strategic decisions in real time, there’s a lot more to these genres that HD2 doesn’t include. Hell, technically you don’t even need to extract, as the only thing successfully extracting gives you is any samples you find… completing the mission counts as a win regardless.
