The game loads surprisingly fast in your browser and looks a bit better than the original thanks to the new game engine. No plug-ins are required.
What’s also cool is that OpenLara offers both third-person and first-person modes. Players can switch at will between these two modes. Furthermore, the framerate has been unlocked and the game can be enjoyed at higher framerates (the original Tomb Raider was locked at 30fps, even on the PC).
