It’s been a while since I’ve played this map to be honest, but from what I can remember, I think the main problem with it is the best parts of the map were woefully underused.
The city that you did a pretty good job on doesn’t have any objectives in it, though is the nicest looking part of the map, as well as the Axis communications and control center on the other side of the bridge.
While the Axis communication center was one of the objectives, perhaps it needs expanding? I’m not sure if you tried to use plans from the original town or if you were going for an adaption of the movie based on the same name “The Bridge at Remagen”, but I would expand the communications and control center and I would also put some objectives within the town and make it worthwhile, other than a simple spawn, it seemed incredibly underused and the bridge needs to be lit up a little, at least within the towers…way too many shadows and places you can’t see it all.
In the movie they had AA guns up one of the hills overlooking the bridge to take on incoming Allied tanks, perhaps you could do something like that? Make it a tank map? I don’t know, just some ideas for you to ponder.
Good luck with redoing/continuing the map and I look forward to playing it once you’re ready. Should you need help with playtesting before you’re ready for a general release, I’ll be happy to help you out.
