We've posted our Shadow of the Tomb Raider review earlier today. Here's an excerpt from the summary:
Shadow of the Tomb Raider succeeds in giving Lara the character growth she needed and also brings the reboot trilogy to a satisfying closure. It does so mostly by refining the strong gameplay foundation set with the previous installments while delivering a great action/adventure experience in terms of storytelling and audiovisual spectacle.
