Metro 2033 is a good shooter. The subject was new and do even now more incentive. In Russian with German subtitles, it's the most fun. Unfortunately, some technical flaws have crept. Opponents AI is lousy and there attacking hordes. In some places, that's just too hard. The graphics is too weak on the chest. Clear the optical effects are able but the rest is moderate.
Conclusion: Good shooters for 10. Because you can not complain.
