Actually my results were not really good.
The best I was able to get is to have all towers (not just some) bugged to some level point, but with soliders climbing up eventually.

Anyway, I just used hex editor to do this.
Google to find some free hex editors.

P.S.
Note that simple notpad editing would corrupt the file.
