If you’re super old school, you might remember Amateur Surgeon as Adult Swim’s very first game on the App Store. If you never played it, it’s basically Trauma Center: Under the Knife for the old school DS, but dripping with Adult swim charm and silliness. Amateur Surgeon was a hit, and Adult Swim went on to release two sequels to the original which all have since been removed from the App Store. As of this morning, Amateur Surgeon 4 (Free) hit the App Store. The fourth installment is a bit of a remaster of the original games, as well as being packed with new content, so there wasn’t a whole lot of reason to keep the old defunct Amateur Surgeon games around.

Last week, Adult Swim graced iOS gamers with its newest game offering, Amateur Surgeon 4. While the game is a somewhat of a re-master of the three original games, it brings with it 100 challenging and gruesome levels, featuring a number of unconventional surgery techniques and tools. In the game, players must master the art of using a pizza slicer, staples, vacuum cleaner, syringes and more in hopes of saving their ailing patients’ life. While the game can be a bit gory at moments, it’s a ton of fun and will keep players engaged as they race against the clock to keep patients alive.

The Amateur Surgeon 4 tutorial does a great job of guiding you through the first few levels of the game, but as you progress, you’ll find yourself more and more on your own trying to figure out how to use your rudimentary tool set to successfully complete your operations.

There’s 100 levels included now, which is way more content than the previous games, and it’s totally free to play. Also, apparently it’s pretty great on the iPad Pro with the Apple Pencil, which is rad as there’s really not many games that are made for that setup.

Basically, it’s oh-so-wrong surgery simulation done oh-so-right, with a consistently satisfying mixture of challenging touch-based gameplay, gloriously gruesome graphics, and Adult Swim’s trademark outlandish humor. And with Amateur Surgeon 4, you can also enjoy remastered and retooled versions of classic levels from the first three Amateur Surgeon games.
