This game suffers from some baffling decisions which cause severe ludonarrative dissonance. One of the main mechanics of the game is to have sex with your party members in battle to restore both your & their health, this is the only means of healing in the game. This is available from the first mission.

However, in the cutscenes which play in-between each mission, you don't canonically have sex with each of the girls until after mission 3, it is established that none of them are comfortable having sex in front of the others until mission 5, and only after the last mission in the story do each of them "find out" that they've all been doing it.

So narratively, it doesn't make sense to use this ability until after the game is already over. Doing it from mission 5 onwards is an acceptable compromise, and the first 4 missions can be completed on normal difficulty without using it.

All that aside, it's a decent shooter with passable gunplay. It gets a lot of comparisons to Left 4 Dead, which is fair by the UI, but it actually reminds me a lot more of Killing Floor. In either case, one thing I wish these developers had learned from their predecessors was to spawn enemies a certain distance away from the player, or at least from designated vents and such. Not just pop them in right on our heads.

While the story & characters are bare-bones, they are at least likeable, and I didn't notice a single translation error, which is rare for these types of games. The dialogue is subtitled in both missions and cutscenes, but sadly there are no subtitles for the dialogue in any of the 3D sex cutscenes, be they the between-mission scenes or the game-over death scenes.

Also the music in this game is great. I know the sequel game has a purchasable soundtrack, but I wish this one did too.
