A new developer diary from the studio behind Lara Croft and the Temple of Osiris offers up a look at some of the puzzles that can be expected in the upcoming four-player sequel.

The video, which you can view below, shows executive producer Scot Amos and lead level designer Jeff Wajcs work through the mirrors, time bombs, gears and falling platforms that need to be manipulated.

Lara Croft and the Temple of Osiris, the sequel to isometric action-adventure game Lara Croft and the Guardian of Light, will launch for PlayStation 4, Xbox One and Windows PC on December 9th.

In Lara Croft and the Temple of Osiris, Lara and her rival Carter are cursed after breaking into an ancient temple. Along with demigods Isis and Horus, they set out to defeat the evil Set and break their bad luck. In a step up from the previous game, Temple of Osiris will feature co-op play for up to four people.
