Shadow Harvest is set in the year 2025. The player takes control over two ISA agents (Myra Lee and Aron Alvarez) which are are deployed as elite black-ops agents on various current and future points of conflict around the globe to cooperatively complete covert operations. Both characters are very different from each other and also have very different special skills. To optimally achieve all mission goals, the player needs to combine Myra's stealth skills, cleverness and athletic abilities with Aron's blunt open battle approach.

Featuring dual character control, realistic graphics and a refreshingly different storyline, Shadow Harvest is a completely new interpretation of the tactical-action genre. Being an ISA agent, the first character, Myra Lee, has a background in espionage and stealth operations, while the other character, Aron Alvarez, is a hard-boiled close combat specialist of US Army's Delta Force. Both characters are deployed as elite black-ops agents on various hot spots worldwide and behind enemy lines to cooperatively complete covert operations.

The plot of the game is highly inspired by the activities of the US army special operations unit ISA (Intelligence Support Activity), but despite its highly detailed and realistic look, Shadow Harvest does not strive to be a hardcore military sim nor does it want to be just another "dual-character-shooter". Besides being a fast-paced tatical action game when playing with Aron, Shadow Harvest also features real stealth and action-adventure elements when playing with Myra. Its refreshingly new mix of features allows new possibilities in interactive storytelling and lets the player dive deep into a thrilling storyline in an immersive and unique gaming experience.

To optimally achieve all mission goals, the player needs to combine Myra's stealth skills, athletic abilities and cleverness with Aron's blunt open battle approach. In many situations the nail biting about whether to go in hot with guns blazing or to use suppression techniques and alternative paths is up to the player. Thanks to its open level design with multi-paths and optional secondary objectives, Shadow Harvest also offers great replayability

With Myra and Aron having a different style, a totally different approach on combat tactics and (obviously) a different gender, one big focus of the game are the witty yet snorty dialogues between the two agents.

Despite its highly detailled and realistic look, Shadow Harvest does not strive to be a hardcore military sim nor does it want to be just another dual-character-shooter. Featuring real stealth and action-adventure elements, its refreshingly new mix of features allows never before seen possibilities in interactive storytelling and lets the player dive into a highly thrilling storyline in an unforgettable immersive and unique gaming experience.

Shadow Harvest is named after a codename for a fictional direct action division of the top secret US Army Special Operations Unit ISA (Intelligence Support Activity). Operating under various codenames (Centra Spike, Torn Victor, Grantor Shadow etc.), the ISA is perhaps the least known and most classified unit within the realm of US special operations. Its existence is denied by the US government. However, over the years various documents and reports became available which gave an insight into how the ISA is structured and into its past and current operations.
