Overcooked 2 takes what was already a great local player co-op game with the original and instantly improves on it the second you get to the menu and see that online play is now also possible. All modes now have some sort of online element to them, which really does make the game a whole lot easier to enjoy if you perhaps lack when it comes to having gamers in your house willing to play it with you, as it really does shine Overcooked in a much better light when adding more people.
Finally, we have versus, where once again you can play it local play, online public, and online private. Here you are trying to beat the other person by preparing and getting out more orders than them, so it certainly adds to the tension and rage if you got that in other modes.
In terms of unlocks, you unlock new chefs to use as you play through the story, which while not having anything unique to them other than looks, they do add to a decent cast of characters to play with.
Overall: Overcooked 2 takes what was already one of the better local play games and improves on it by adding online play, new recipes, and just adding more to what was already a fun/crazy game to play with loved ones and now random people on the Internet. Easily one of the best party type games released so far this year, and worth checking out if you have kids or just fancy playing something that is a bit different to mix things up a little.
