Due to EA27 update, previous remastered version does't work any more. Fortunately, Trench Maze is one of a few maps that I still keep the unity project files. I fixed the map for EA27, also made a bit upgrade. Now we have Trench Maze with background and ambient sounds.
Anyway, just enjoy the thrilling trench warfare. XD
Attention
The playable size of map is still 80x80m (not extended). And this is still a CQB map.
