In the teaser, released on the movie's Twitter page, Lara takes aim with a bow and arrow as she runs through a forest, plummets hundreds of feet into a raging river and crawls through a dark tunnel.
The full trailer for the forthcoming Tomb Raider will be released on Tuesday.
The new style is very different to Angelina Jolie's interpretation of action heroine Lara.
She wore a tight black T-shirt and shorts with two seriously huge guns strapped to her hips.
Rumors of a new Tomb Raider began swirling in 2007 and GK Films bought the rights in 2011.
But it wasn't until 2015 that GK confirmed Warner Bros. and MGM had boarded the reboot with Roar Uthuag as director.
Alicia plays the daughter of long-lost English explorer Lord Richard Croft, played by Dominic West, who sets out to find him.
The movie is set to be released on March 18.
