Gal*Gun: Double Peace is a rail shooter bishojo game which focuses mainly on anime boobs. The same policy has also been extended upto its DLC by the developer Inti Creates.
Pheromone Z, the game’s new DLC will take the experience further as it will let the game’s sight zoom to see through the clothes instantly. The DLC will cost $90 (you read that right) and in today’s modern times, where Porn is just a click away, this is worse than daylight robbery.
In case you are planning to get Pheromone Z, you can get it from here.
