steam thread Download lib32-glibc-2.20-6... from
http://seblu.net/a/arm/packages/l/lib32-glibc/
Open with an archive manager and then go into user, lib32 (in archive)
Now copy the following (out of the archive) and put them in the lib of This War of Mine's installation directory (~/opt/This\ War\ of\ Mine/lib/ for me )
libc.so.6
libc-2.20.so
libpthread.so.0
libpthread-2.20.so
librt.so.1
librt-2.20.so
That *should* do it
