• Add this line to your XCOM2.sh file at the beginning to get the Linux native version running:

LD_LIBRARY_PATH="../lib/x86_64/:${LD_LIBRARY_PATH}" 

• XCOM2.sh file should look like this:

#!/bin/sh
LD_LIBRARY_PATH="../lib/x86_64/:${LD_LIBRARY_PATH}"
GAMEROOT=$(cd "${0%/*}" && echo $PWD)

if [ -z "${SteamAppId}" ]; then
    echo "XCOM2 not launched from steam, launching steam with steam://run/268500"
    steam steam://run/268500
    exit 0
fi

HAS_CATALYST="$(grep fglrx /proc/modules)"
if [ -n "${HAS_CATALYST}" ]; then
    LD_PRELOAD="../lib/x86_64/libtcmalloc_minimal.so:${LD_PRELOAD}"
    export LD_PRELOAD
fi

unset LC_ALL

cd "$GAMEROOT/bin"

"${GAMEROOT}/bin/XCOM2" $@
RESULT=$?

exit ${RESULT}

Enjoy the game!

Native Linux version does not run without this line in the beginning of the XCOM2.sh file:

LD_LIBRARY_PATH="../lib/x86_64/:${LD_LIBRARY_PATH}"

Enjoy the game!
