MECH WARS is split into a Single Player mode with a huge campaign and a competitive Multiplayer Online Battle Arena (MOBA) mode. Both modes are connected and achievements of one mode will affect the other one. The game takes place in a post-apocalyptic scenario and narrate an immersive story. The game includes a feature-rich crafting part which enables players to construct, modify and create mechs, creeps, weapons and equipment and use them in single and multiplayer.

The game progresses in two phases. In the first phase Mechs are built and prepared for combat. Afterwards every Mech is provided with a unit squad (creeps). Unit types will be built by the automated factories, which have to be conquered by the player. The right Mech and unit configuration is mandatory to dominate the battlefield.

In the second phase, which is the battle phase, every player uses his armed forces to battle the enemy.
