Lara Croft returns in Temple of Osiris, where new challenges and puzzles await her. In the second Developer Diary, Executive Producer Scot Amos is joined by Lead Level Designer Jeff Wajcs, who discuss the difficult task of perfectly challenging a player. Take a peek at the mirrors, time bombs, twisting gears, and falling platforms you’ll need to manipulate to solve your way out of trouble, alone or with friends.
