Covert Ops: Nuclear Dawn

Chase the Express is a played from a third person perspective, with fixed cameras that focus on the player camera spread across each explorable area in the game. The main focus is to explore an armoured train, visiting each car, searching for useful objects, while dealing with hostile enemies - with the game borrowing notable elements from both Resident Evil and Metal Gear Solid.

Combat focuses mainly on the use of firearms that the player can find during the course of a playthrough, with additional ammo either found in a level or dropped randomly by some enemies, with each weapon featuring parts that can be used to improve them. Alongside weapons, enemies can be engaged in hand-to-hand combat, though players can opt to use stealth to avoid combat and get around enemies; enemies become alarmed if they should spot the player, until they either evade or eliminate pursuers. Any damage from enemies can be treated by finding and using first aid kits.

Following a visit to St. Petersburg, French ambassador Pierre Simon makes his return to Paris aboard a NATO armored train called "The Blue Harvest", accompanied by his wife Catherine, their daughter Jane, and Simon's secretary, Philip Mason, are guarded by a NATO team led by Lieutenant Jack Morton. Shortly after the train nears the borders of Ukraine, a terrorist group known as the "Knights of the Apocalypse," led by ex-KGB agent Boris Zugoski, attacks the NATO team and boards the train. Boris reveals his intentions to ransom Simon and his family for $20 billion from NATO along with safe passage into France. Jack, the only survivor in the NATO team, finds himself placed under the command of a United Nations counter-terrorist agency, who instruct him to rescue the ambassador and his family as well as dealing with the terrorists.

Gaining access to the interior of the train, he manages to rescue Pierre and Mason, with the ambassador asking him to find Catherine and Jane. Searching for them, Morton encounters Christina Wayborn, the only surviving member of the ambassador's protective detail, who works alongside him, and Sgt. Billy MacGuire, a grievously wounded soldier. After rescuing the ambassador's family, a rescue team arrives and recovers them from the train.

The game received "mixed" reviews according to the review aggregation website GameRankings. IGN criticized its gameplay for bad controls and game design despite praising the graphics and stating that the game had "detailed environments and solid player models". Daniel Erickson of NextGen called it "A good weekend rental with nice graphics but nothing to really sink your teeth into." In Japan, Famitsu gave it a score of 30 out of 40. Uncle Dust of GamePro concluded, "Twitch-oriented gamers should pass on this rather sluggish thriller."
