Sometimes history can be more captivating than legends!
Winter War: over 500,000 Soviet soldiers attack Finland, a country with a population of 3,700,000, and the Finns drive them back, inflicting 5 times their own casualties. Continuation War: the Reds return with a total strength of 1,500,000 - almost half of the entire Finnish population - and the Finns stop them again. Finland’s survival in these two brutal wars against an enemy so vast was a true historical miracle. A miracle of heroism and valor. A miracle of the Finnish spirit of liberty.
Immerse yourself into the (hi)story-driven gameplay
Primary and secondary objectivesComplete numerous objectives grounded in history and narrated by a number of historical characters.
Faithfully recreated historical units
Command the Finnish ski troops and captured Soviet vehicles, including BT-7, T-34, and KV tanks. Purchase German Pz-IV tanks, StuG assault guns, and Ju-88 bombers. Make use of pre-war British Bristol Blenheim bombers, covered by Dutch Fokker and US Buffalo fighter planes.
Upgrade your units to newer models
Make sure your forces are always up to date and up to the task. New models become available at historically accurate points in time.
Train your troops and choose equipment
Gain combat experience
Choose various skills for your men as they gain combat experience.
Combine units from different classes
Compose your own force from ten classes available: Infantry, Artillery, Tanks, Reconnaissance units, Assault guns, Armored trains, Anti-tank guns, Anti-aircraft guns, Fighters, and Tactical bombers. Utilize their unique skills and equipment to maximum effect.
Acquire diverse equipment
Equip units with various special equipment, such as Machine guns, Mortars, Smoke grenades, Anti-tank rifles and Molotov cocktails, Winter equipment, and many more.
Use transport vehicles
In the harsh Finnish winter, speed may be the difference between life and death. Provide your units with vehicles to improve their mobility, or have your Infantry use skis to outmaneuver the enemy in winter operations.
Use elaborate combat mechanics to overcome any foe
Manage Lethal vs Nonlethal damageThere are two types of damage: lethal and nonlethal. Dealing nonlethal damage to your enemies will make them surrender. Different units are prone to deal either lethal or nonlethal.
Use terrain differences to your advantage
Tanks are vulnerable in difficult terrain and cities, while Infantry can occupy buildings or hide in the forests to gain large defensive bonuses. All units suffer large penalties in swamps or while crossing a river, etc. Be aware of your surroundings, and use them to your advantage.
Take the “line of sight” and the “zone of control” into consideration
Some terrain and buildings obstruct firing unless you are using artillery or mortars. Approaching an enemy unit up close will finish your movement, unless you are using a Recon unit.
Activate various skills and equipment
Use incendiary or subcaliber shells to maximize your damage to the enemy. Order forced march in the most desperate situations. Employ aerobatics to increase your air force efficiency. Use your HQ skills to affect the entire battlefield.
Use a complex spotting system that represents the importance of reconnaissance
Call upon the air and ground reconnaissance to gather intel about the enemy before ordering your troops forward. No one likes to be ambushed.
Adapt to various battlefield conditions
There is a day-night cycle in the game as well as weather types such as frost or rain. All of these conditions impose penalties that must be countered with special equipment and skills. The finest of your troops may even use such conditions to their advantage. Use the cover of the night to sneak up on the enemy, or strike when the foe is freezing and immobilized.
Utilize the most advanced supply and infrastructure system in the genre
Ammunition and fuel
All units have limited ammo and fuel. Without ammo, your units cannot fight, and without fuel, your vehicles cannot move - and any aircraft will simply crash.
Supply hubs
Generate supplies and transfer them to your troops throughout an entire system, like a heart pumping blood through veins.
Supply points
Connect different infrastructure facilities and redistribute supplies. Supply points also allow your troops to change special equipment and renew its charges.
Airfield
Allows aircraft units to land for refueling, repairs, and refit of equipment. Damage to the airfield would also damage all landed aircraft.
Seaport
Allows resupply and change of equipment for naval units. It also generates supplies, if there is a maritime hub nearby and the Seaport is not under enemy blockade.
Damage the infrastructure
All infrastructure facilities can be disabled if their HP drops to 50% or lower. It will then gradually regain its HP and its functionality. Strike at the enemy facilities to prevent them from resupplying.
Cut off the enemy supply lines
All infrastructure facilities are considered connected if a simple truck vehicle could move between them in one go. If you put your unit between the enemy facilities, it would create a zone of control, and prevent the enemy from transferring supplies. Leave the enemy units without much needed ammunition and fuel, then hunt them down.
Make sure your own units are supplied
There is a limit to how far your supply vehicles can deliver supplies - make sure you take that into account when planning your next offensive.
