Hey All I just released a patch unlocking Slaughter House without a need to go through Expedition mode. This is to address the issue raised in the first review. Generally speaking game have two modes: - Expedition mode - this is hunt or be hunted experience, where the enemy will try to sneak on you and run into wilderness as soon as you notice his presence. - Slaughter house - this is survival mode which is similar to Dinosaur Hunt game. I hope this will improve the experience for players expecting more of a Dinosaur Hunt type of game. Thank you for your purchase. ANPA.US
