It's early days yet; the game's set for release in the first half of 2016 for PC and current-gen consoles. The "all-star development team" working on it includes Steve Hart, formerly of fellow sniping game Sniper Elite V2.
“The Sniper: Ghost Warrior franchise is one of the most popular in the CI Games portfolio with over 5.5 million copies sold, so we’re investing a significant amount of effort into the third installment,“ said Marek Tyminski, CEO, CI Games. “We’re fully committed to creating a AAA franchise that gamers can rely on for the ultimate first-person sniper experience.”
Past entries have been set in tropical climes, but Ghost Warrior 3 will take place in Eastern Europe, with the player stuck in the middle of a conflict between three rival factions. The developers promise "non-linear, sandbox-style gameplay" on large, open maps, with highly replayable missions.
Ghost Warrior games have been decent enough, but held back by some middling level design and poor AI. Hopefully CI Games can fulfill the series' potential this time around. We can always do with more sniper games after all.
