As the name would suggest, Crash Bandicoot 2 is the sequel to the original Crash Bandicoot. These were 3D platform games and this is a case where the sequel actually improved upon the original. Crash Bandicoot 2 was released in November 1997, about a year after the original.
The game has a few unique gameplay characteristics. Attacks include jumping on enemies, spinning like a tornado and sliding across the ground (which also allows Crash to jump higher). Crash can also perform a body slam to break some objects. Boxes are scattered about that can be broken by crash. Most have typical power up items or fruit to collect that will eventually get you an extra life. however, some boxes when broken cause objects in the level that were previously intangible to solidify. There are also TNT and Nitro boxes that explode and boxes that can make all such boxes on a level explode at the same time.
Overall, the game got good reviews and this sequel was generally considered to be a little better than its predecessor. It was also one of the bestselling games on the system. Both are good games and as exclusives to the PlayStation were games that all PlayStation owners should at least try. The good news is you can play this game on more modern systems.
Crash Bandicoot 2 was released on the PlayStation Network in 2008 and a remastered version is included in the Crash Bandicoot N. Sane Trilogy that was released on the PlayStation 4 in June 2017. This trilogy also includes remastered versions of the original Crash Bandicoot and Crash Bandicoot 3: Warped. Purists may want to track down the originals but this is a pretty good substitute and has some improvements as well.
