No revenue estimate for GOG — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $165.1K — a different platform, not this one.

Chaser

John Chaser is a man without memory or friends. Alone, in the middle of a bloody conflict, he is trying to find out who he is. His extraordinary fighting abilities enable him to survive, but they raise more questions than they answer. Chaser awakens on board the spaceship H.M.S. Majestic. He doesn't know why he is being sought by men in black uniforms and what they will do to him when they find him… The story leads you from the H.M.S. Majestic to Montack City on Earth, then on to Siberia and finally to Mars, where the trail ends and hopefully the truth can be found. A gripping story full of intrigue, plot twists and believable characters. Unique game design for a shooter, focused on the story and its presentation through long, thrilling cutscenes. Fast-paced action with over a dozen weapon types and a skill-heavy "bullet time" mode.
