The melee attacks and Waffenaufrüstmöglichkeiten are quite practical, and truly succeed in the game thanks to the 4A engine again a leap forward. The ability to be able to play both games in two styles, I think that's great, as is the directly integrated DLCs.
40 euros are a real bargain, so I can warmly recommend the bundle any non connoisseur of games only warmly for the two metros. For those that already knows both games, should the initial purchase think twice - and to set in the download version in doubt only the significantly optimized Metro 2033 Redux.
