If you liked the Half-Life series or thought they were alright, you'll most likely really like Entropy: Zero 2.
If you liked Entropy: Zero 1, you'll love Entropy: Zero 2.

The game feels almost exactly like Valve themselves put each piece of the game together. Every map looks interesting, the combat is very fun, the music is great, and the story is extremely intriguing.

Like Entropy: Zero, combat is not bullet-spongey unlike Half-Life 2's hard difficulty. Guns hurt no matter who's doing the shooting and you have to control yourself when firing unless you want a miss rate of 80%. The addition of being able to command combine soldiers is also a nice touch (which is straight from Gordon commanding rebels in HL2, but E:Z2 puts visual effort into it that makes it look pretty). The new weapons are also pretty diverse and fun to mess with too.

The story is once again told in a very pleasing way. It is once again never in your face unless it has to be, and it makes sure those moments are limited as much as possible by merging them with gameplay as much as possible. There is never a dull moment. Even the down times have great visuals to keep you interested.

Entropy: Zero 2 has its own version of the gnome achievement from Half-Life 2: Episode 2, but, without spoiling too much, the game will make you want to do it (in a good way and not in a "I cripple myself heavily by not doing this" way) and try to make it fun to do rather than it feel like a chore. And the achievement is made as stress-free as possible (except for the carrying part, but removing that would remove the fun of carrying an object across nearly an entire game, it's the greatest thing ever).

To summarize, Entropy: Zero 2 expands on what made E:Z1 fun and adds much more to it, with exciting-to-use mechanics and many new enemies and environments, all combined into a great story.
