After I quit my job in government, I ran a small bar. Five years doing very well, I got a call from an organization called AZ7 that has contact with the government, they revealed to me that there was a project of a trans-space machine, but it was canceled during a raid by a secret organization and my friend Zaco was also murdered that day, this is a secret case known only to me and a few high-ranking agents. After exploring a lot of records and documents, I found the clues of that terrorist organization, a secret underground but uncertain headquarters and of course I will go to explore their facility. - An action and puzzle game that keeps you focused on every move if you don't want the game over - Use two fingers to place bombs when you get bombs - Use three fingers to change camera view
