Halo 3: ODST is one of those sleeper hits that as time goes on, you feel more and more fondness for. I’ve played it countless times, as I have all mainline Halo games, but each time I do I find that ODST has something new for me to appreciate, whether it be fine details, B plots, deep mysteries or a strangely compelling mood. It’s not the most active fun, nor the best designed nor the most complete package, but despite this it does manage to be my guilty favourite from the franchise.
