Surgery Master is a game where you get to play a surgeon and have to operate on patients with a variety of different ailments. In all, you can carry out over a dozen different types of operations. To do this, you'll need to use all sorts of different surgical tools like a scalpel, laser, needle, hammer, etc.
The gameplay in Surgery Master is pretty similar to other titles like Trauma Center. From the drop-down menu on the left, you can choose the tools you want to select. Then, all you have to do is touch and slide your finger around on the screen to use them intuitively; use the scalpel to cut, the needle to sew, etc.
At the beginning of the game, you'll operate exclusively inside the hospital. However, as you complete levels and gain experience, you'll be able to operate from less comfortable locations, where things will be much more difficult. You'll even have to go to some special locations in emergency situations.
Surgery Master is an excellent Trauma Center-style game. It has great graphics and a huge variety of operations and emergency situations. You can stitch wounds, perform heart transplants, complete emergency first-aid treatments, and more.
