I've got a lot of time for this game! Credit where it's due, I think the worlds in this game are really quite special, and each is crafted neatly and with care, which is impressive considering it doesn't have a lot of time to tell you its story. Environment design in a game that is semi-procedural like this must be quite difficult, but R2 manages it well!

Plus, it's just very good fun to do the shooting, and the killing and such
