Spelunky is a platformer, which usually means one player, but
Spelunky gives you the option to play with up to four players. From the Main Menu, you can choose Play Game, Play LAN Game, Player Stats, Leaderboards, or Help & Options.
When you choose Play Game, you can choose either Adventure or Death Match. In Adventure, you can then choose to play alone by just selecting one character or with up to 3 friends (four players total). There are 12 characters unlocked from the beginning and 8 more that you can unlock as you play. When you first start, you will be told the story of Yang. Your explorer has found Yang’s Journal and it will serve as your training guide on how to play the game. After you get past it, you will receive a key to unlock the tomb and actually start the game.
Every time you enter the tomb, the walls will shift, which means that every single time you play, you are playing on a different board. The concept is simple. You just have to make it from the entrance to the exit. In your way are a variety of monsters, traps, potential deadly falls, and more. There is also a lot of treasure for you to find. Given infinite time, you could go slowly and be very careful and find everything, but you have only two and a half minutes. At that point, a ghost will be alerted to your presence and come after you. Unlike the rest of the enemies, you can’t kill the ghost. You can stall him a few seconds if you have a camera to take his picture, but you still better be running for the exit as quickly as you can! The further you get into the tomb, the more levels you will unlock. Keep going and you might just make it out alive and rich.
Death Match lets you compete against each other. If you stand still, the game will target you. Otherwise you can throw bombs at each other, push each other into lava or any other natural killing element, or pretty much any other way you can think of to kill your opponent. You can specify the number of times one player has to win to be declared the champion. You can also choose the board you want to play on from any of the levels that you have unlocked, plus some others that are built in.
