Hitman Sniper is a single-player shooting game where you take the role of Agent 47. Your objective is to eliminate targets from a fixed sniper perch, using careful observation and planning to create accidents and chain reactions. Each mission requires precision and timing to achieve a high score and complete optional challenges.

The gameplay revolves around scoping large, detailed sandbox levels to locate targets and discover environmental interactions. You must manage your weapon's reload cycle and account for bullet drop over long distances. Progression unlocks new rifles, upgrades, and special abilities to approach scenarios differently.

The game mode consists of a lengthy campaign with individual contracts and an endless zombie survival mode. Both modes test your accuracy and speed, with leaderboards tracking global performance. The touchscreen controls are designed for aiming, holding breath, and firing the sniper rifle.
