Call to Arms brings modern warfare into a hybrid of real-time strategy and direct action. Players can command squads across rural areas, factories, railway stations and towns, using destructible surroundings and available cover as they advance toward objectives. The premise supports two complementary perspectives: coordinating a force from above, or taking control of an individual soldier and entering the fight firsthand.
In strategy mode, players direct dozens of units, position squads in cover, flank opponents and support allies. The game also gives players control of vehicles, including tanks and helicopters; tank operation includes choosing ammunition, while helicopters can provide air support in online matches. These options distinguish Call to Arms from a strategy game confined to issuing orders, pairing battlefield planning with hands-on control of soldiers and machinery.
The listed formats include single-player, multiplayer, PvP and co-op, with online variants for both PvP and cooperative play. Its defining appeal lies in moving between tactical direction and direct participation in a modern battlefield.
