Get ready for an adrenaline-pumping adventure in the Wild West! In Colt Express, you and your friends transform into daring bandits, ready to plunder the Union Pacific Express. The goal is clear: accumulate the greatest fortune in cash and jewels before the train reaches its destination. But it won't be easy, as other outlaws are also eyeing the same treasure, and Marshal Samuel Ford is hot on all your heels.

The game unfolds over five thrilling rounds, each divided into two crucial phases. In the first phase, 'Schemin'', players secretly choose their actions, playing cards onto a common pile. The big trick is that some cards can be played face down, adding an extra dose of bluff and uncertainty. Instead of playing a card, you can also choose to draw more cards into your hand, adjusting your strategy in real-time. In the second phase, 'Stealin'', the cards are revealed, and actions occur in the order they were played. This is where chaos ensues! Your most brilliant plans might go awry due to unexpected actions from your rivals or even a miscalculation of your own.

The major highlight of Colt Express is the 3D train, which serves as the stage for all your mischief. Bandits can run through the cars, climb onto the roof, punch other robbers, shoot them, rob unsuspecting passengers, and even manipulate the Marshal's position. Each car starts with valuable items like jewels, money bags, and suitcases, waiting to be stolen. To pick up an item, you need to be in the same car and play a 'Steal' card. But beware, competition is fierce! Punching an opponent makes them drop one of their items and knocks them into an adjacent car. Shooting someone (either in an adjacent car or, from the roof, anyone in sight) adds a bullet card to your opponent's deck, which can hinder their future moves. And if the Marshal catches you in the same car, prepare to take a bullet too!

At the end of the game, the bandit who fired the most bullets receives a $1,000 braggart bonus, but the true winner is the one who bags the richest haul. Each character has a unique special power, such as starting with an extra card or pocketing an item when punching someone, adding even more strategic depth and replayability. Get ready for lots of laughs and tension in this train heist!
