Queen – “The Trap” [Campaign 1, Mission 4]

There is a tank on this map, but it cannot be seen from the bridge. To trigger the cutscene, you need to approach the nearest tree near the bridge. If the cutscene doesn't play, it's a bug. If you are playing version 3.0 using a mod, this is another example of a poorly implemented feature. I don't know how it works in the "Gold Edition." My advice: play on version 1.x. There will be fewer bugs ;). And in the future, too. You can also try replaying the mission if the previous suggestions don't help :).
