If you read the parts in bold, it sounds much more promising.
This is a map. At spawn, there are many paths. Then you go into a factory. There are a few paths after that. Then you get mein shaft. Actually, you get to a mine shaft and there are many elevators. Afterwards you split up. Then you meet up and call the A-team. Actually, that’s just what console says: there’s no theme song. Only a chopper comes. Then there’s a surprise. You reach the bunker afterwards, but zombies can kinda walk as fast as the chopper. If you keep them out you win.
