SAS: Rogue Regiment is a co-op stealth action game where players take on the role of SAS and allied operatives completing objectives behind the lines in WW2. The German soldiers work with baked in behaviors such as patrolling, and have random special events that can happen such as static guards turning or moving patrols reversing direction. Players, using a variety of characters with special equipment, are supposed to stealthily evade or pick off the enemy soldiers while completing objectives.
In this scenario three players, each controlling one SAS operative were in play. I chose a sniper, who was equipped with a long range rifle, a ghille suit that allow for camouflage at the edge of woods without having to spend an extra action to hide, and a climbing kit to scale rock faces. A second player took an SAS operative armed with a handgun, grenades, and a climbing kit. The final player took a demolition specialist with a Sten gun.
The players deployed in the, from the picture POV, bottom left. There were three objectives: A supply cache in the mid left to be blown up, a supply cache (not yet placed in the photo) on the far right, and an officer to assassinate in the middle. Completing those three objectives and exfiltrating all operatives would lead to the best final score.

Early in the game the demolitions operative split off to work his way through the woods to set a player determined timed explosive of the first cache. Meanwhile I and the other player with a climbing kit had our character scale the rocks.

Due to overlapping sentry sightlines we ended up killing very few German in the early part of the game, though I was able to successfully sneak behind the officer and stab him unseen while the grenade carrying player worked forward to find a position to toss grenades at the second cache.

While he got in position that was uncomfortably squeezed between a patrolling German motorcycle with an MG42 on it and a clump of guards, I worked my way back towards the rocks and killed an isolated static guard with a silence knife backstab.

Finally, the only good choice was to go loud as the grenade carrying player used all their actions to toss grenades at both the supply cache and the motorcycle. Both targets were destroyed, but the Germans were on full alert and reinforcements started pouring in.
Since the grenades had been tossed from a hidden position, my sniper standing on the rocks decided to take all the initial heat from the enemy troops while the operative downfield remained unseen and tried to work their way back to the exfiltration point. The demolition operative unloaded on a static guard with his Sten gun and tossed a timed explosive into the road in the hopes it would blow up as German reenforced passed it. He then retreated back to the exfiltration point after taking some wounds.

My sniper fired until his rifle was empty and then jumped down from the rocks after being wounded.
The final operative (now being represented by the Sten gun holding mini after dropping and snapping his grenade mini) was able to jump onto the rocks and back down on the other side, but it was too slow as German reenforcements swarmed and gunned him down.

The whole game took about 3.5 hours, played with one person who had never played this game before. The scenario felt just the right size, not too bloated or too easy.
