Alpha Black Zero: Intrepid Protocol is a shooter that takes the player with its storyline to 2366. The game is about taking control of a group of mercenaries who go on missions. The level of difficulty of the challenges implemented in individual missions increases with the developing plot of the game, which is presented from the point of view of a third person. The player takes on the role of Colonel Kyle Hardlaw, who is the leader of a highly specialized group of commandos.

The plot of the game begins a moment after Colonel Hardlaw was unjustly accused of murdering a group of high-ranking officials. This makes the game multi-threaded, because the colonel must not only face the adversities he faces while implementing his plans, but also look for ways to clear himself of the charges.

Successive missions are very diverse and intertwine tasks that require the use of force to solve, as well as spy puzzles. You should be vigilant, because during the game more political conspiracies emerge that can help Colonel Kyle clear himself of the charges, but also betrayal that can make it difficult to complete the next missions.
