Travis learns from Dr. Sonia Rand, inventor of the time machine, that a butterfly was brought back from the past on the last safari.

Ryer gets in contact with one of the tourists, Ted Eckles (spelled Eckels in the film), who informs him it was his friend Christian Middleton who was responsible.

Middleton is discovered dead, but Ryer manages to retrieve the butterfly, get back to TSI and enter the time machine.

Along the way, the player can earn points for collecting items, killing enemies, completing the level within a certain time and exploring all the rooms.

Most weapons rely on collectible ammo, but the electric prod only needs to be charged by holding down the fire button before use.

The game received criticism for its password-based save system and praise for its single-cart multiplayer mode.
