War Blade.

Banks, an agent of the British SOE, is tasked with rescuing a French resistance fighter from a hidden Nazi bunker. With the help of a German Nurse and a ragtag group of allies, Banks must journey to the belly of the beast. With his commanders already suspecting the bunker to hold much more than prisoners and a group full of fragile personalities to deal with, Banks faces dangers from all fronts. Always outnumbered and outgunned, Banks and his group must use their guile to outwit the enemy and survive the deadly mission.
