To collect gems or relic pieces, tap the urns that hold them. They are indicated by a glow. Lara does not have to be near them.
Enemies
Do not stand directly in front of an enemy at the end of your move. Each enemy has a specific strategy that can be used to defeat them. Snakes: They are immobile. Approach them from the side or back and Lara will kill it with her pistols. Do not occupy the space directly in front of a snake. Because they never move, you may get an opportunity to shift it out of the way by using a switch or kill it by guiding a saw blade to it. Lizard Men: They can detect Lara up to two spaces ahead and will hop up on their hind legs and begin chasing her. They will follow her exact path. You can move over a cracked space to send them falling off to their death. If a Lizard Man drops off a cracked space on a wall, it will survive but will stop chasing you. Giant Spiders: They follow a set path and will move one space each time Lara moves. Approach them from any angle except from the front will let Lara shoot them. They can sometimes be set off to a different route by using switches.
Movement
Move Lara through each level by swiping in the direction you want her to travel. You do not have to be concerned about changes in elevation, as she can climb walls or hang from ledges. Lara can reach any diamond that is marked with a line connecting it to your current location. Some spaces will have cracks before being stepped on them. Lara's first step on such a location will cause the space to partially collapse. Returning a second time to that location will be deadly. The same type of crack will appear on walls. Landing on a cracked wall space twice will not cause immediate death, but will cause Lara to fall down. She will survive if there is a useable space below her.
Spear
Lara normally does not have a ranged attack unless she finds a spear. Move to a space with a spear on the ground and Lara will automatically pick it up. It will be stored for later use. To throw the spear, you must be on the same level as your target and have a clear path. Valid targets will glow white. Although your spear will be gone after thrown, it will result in a one hit kill.
Switches
Activate switches by moving Lara to the space they occupy and tapping on them. She will use her hands or feet to use as needed.
