It looks like the Apple love continues. Last week saw the announcement of Portal 2 heading towards the Xbox 360, PC and Mac. Now not only has the biggest zombie game, Left 4 Dead, been confirmed for the Mac, but the sequel, Left 4 Dead 2, as well!
According to the L4D Blog, neither game runs through emulation, but "native code." Both games are also cross-platform compatible, meaning that Mac and PC players can get their game on with each other with no hassle at all. Valve also confirmed cross-platform ownership of the games. If customers own one on either platform, they own it on both, it's a pretty neat and much appreciated approach.
No details on system requirements yet. Both games are planned for a Spring release on the Mac OS X this year.
