Warhammer 40,000: Dawn of War: Winter Assault/No Retreat!

At the start of the game there is a short intro. After the intro the game starts and you have five squads of Imperial troops, commisar and command squad. First of all construct your max amount of tech engineers. Make two imperial squads capture the two command posts near the two gates. After capturing them, build listing posts on them, and start build turrets around them, as there will be swarms of chaos troops pouring in every 2–3 minutes.
