Call of War: Free WWII Real-Time Strategy Game by Bytro Labs 144

Call of War is a free World War II real-time strategy game from Bytro Labs, available on PC, mobile, and Steam with shared data. At the start of a match, you pick from over 100 real countries and choose either a 1939 or 1942 map. You develop industry, research technology, and build land, sea, and air forces to play in real time against as many as 99 other human players.

Call of War Core Gameplay Loop

Capture provinces to gather five resources: food, steel, oil, rare earths, and money. Work through a tech tree of more than 120 units, unlocking infantry, armor, ships, aircraft, and nuclear weapons. Build barracks, factories, shipyards, and airfields in cities to produce units in real time. Use diplomacy to form alliances and trade, or drop atomic bombs to make opponents concede. The first player or alliance to hit the required victory points (VP) wins.

Victory and Maps

For VP, every province is worth a fixed 1 to 20 points, with capitals worth around 20 points. A solo player needs to reach the required VP, generally 60% of the total. An alliance needs the required VP while having at least 3 living members in the alliance.

There are several map types, such as 1939 Europe, 1939 World, 1942 World, Pacific, Americas, Middle East, and Speed (3x faster), among more than ten options. Terrain types include plains, hills, forests, deserts, cities, ports, airfields, and resource points, all of which affect movement speed and attack/defense stats.

Resources and Economy

The five basic resources are food, steel, oil, rare earths, and money. Resources come from provinces themselves and buildings like industrial zones, infrastructure, ports, and airfields. Spending comes from daily unit upkeep, research, and building production queues. You can trade on the market by posting buy or sell orders with money, or trade directly with alliance members or other countries.

A useful trick is to raise the "Rare Metals" price in the first 3 days and sell high to quickly get money and expand factories. Oil is more important than steel, steel is more important than rare earths, and rare earths are more important than food. Countries going heavy on armor or air power should first capture provinces rich in oil.

Production and Supply

• In cities you can construct barracks, tank factories, shipyards, airfields, research labs, and nuclear reactors. On non-city land you can build infrastructure (+25% resources and movement speed), bunkers (added defense), and radar (extended vision range).

• Units must be inside your own or an ally's supply range every day, or they take attrition damage and eventually defect. Supply travels by rail or by sea through ports from the capital to the front line. If it's cut off, you'll need air drops or temporary airfields to keep them alive.

• Higher-tier factories let you queue 5 production orders at once. Queueing 8+ hour batches in the early hours when fewer players are online reduces the chance of getting hit by airstrikes.

Diplomacy and Alliances

On any given map you can form 1 alliance of up to 5 players, plus a few non-aggression pacts. Alliance members share vision and supply and can win together.

There are two advanced diplomatic tactics. The first is "gunboat diplomacy": fight first, then negotiate, forcing the opponent to hand over VP provinces. The second is the "shadow alliance": stay publicly neutral while secretly selling resources to both sides, buying time to build nukes.

Call of War Real-Time Tactics

• By timing your strikes to the second, you can have multiple units arrive from different distances at the same time, creating a local 5-to-1 advantage. Use the "+30 sec / +60 sec" buttons to adjust timing.

• The fake attack plus jump-drop trick sends 1 air unit to pretend to hit Province A, drawing out the opponent's interceptors, then your main paratroopers and transports jump straight onto the opponent's capital.

• The fewest players are online between 00:00 and 06:00 in-game, making it easier to land nukes or amphibious assaults.

• You can split tasks between PC and mobile: use the PC for the careful production queues, batch air deployments, and long diplomatic messages, and use your phone to tap buildings, check radar, and pull alarms on the go.

Example Opening Strategies

• Germany, 1939 Europe: Day 1 research Light Tank I and Interceptor I. Days 2-3 annex Poland, upgrade industrial zones to level 2, stockpile 5,000 oil. Day 5 mass-produce Medium Tank II and Interceptor II and blitz France in the west. Day 7 grab the VP provinces along the English Channel, establish air superiority over Britain, then decide whether to go naval or push into the Soviet Union.

• Brazil, 1939 World: Days 1-4 build only infrastructure, sell food for rare earths, and wait for the "Destroyer + Transport" tech. On Day 5 use your navy to grab small Caribbean islands and raise a South American army. On Day 8 ally with either the US or the Axis to give them naval bases in exchange for VP provinces, positioning yourself as the "South American second winner."

• Soviet Union, 1942 World: Rely on your huge territory and winter terrain to hold the line early. Around Day 10 counterattack with Medium Tank III and rocket artillery, supported by strategic bombers to dismantle German industrial zones. For the nuclear path: uranium mine → reactor → atomic bomb; you can have a nuke ready by Day 12.
