If you’ve been a gamer for more than five years, you’ve probably heard of Spelunky. If not, you’ll love it.

The game was launched in 2008 for the PC, and has been an underground favourite ever since. Now updated for the new generation of gaming action—with enhanced graphics, a bizarre number of scenarios and a co-op mode—it has all the makings of an addiction. There are funny monsters, neat puzzles and a whole set of levels that you’ll have to play for weeks to master. No two plays are the same, so keep plenty of water handy.
