Jack Liu: This game uses 3D character which reminds me of Counter Strike I played when I was small. It really has a huge map and player can spend some time to explore the map which is fun for me. However, I do expect there are more decorations in each scene. The level number is straightforward and it increases the difficulty for each level which makes me know which level am I in. The zombie looks a little bit scaring but it's a great game overall!
