From TRLE Wiki
The HAMMER is a deadly trap that will hurt Lara when she is hit. When 2 HAMMERS are placed opposite of each other, it will mostly kill Lara in 1 hit. It will also destroy any PUSHABLE_OBJECT it hits, the object will shatter into pieces when it's hit. The HAMMER is also used in the Obelisk puzzle. It requires an OCB code to work.
