Commander Wars

Commander Wars is an open source turn-based strategy game that tries to translate the experience of playing the Advance Wars saga to Android smartphones. And it achieves its goal with flying colors. This game features gameplay that's practically identical to the gameplay that made the legendary Intelligent Systems saga so popular.

You'll have complete freedom when creating a new game. At your disposal, you'll find tons of options when you create the scenario, from randomizing the terrain's layout to choosing the number of opponents controlled by the AI that you'll fight against. So you can play either a 1v1 duel against the AI or a battle between four clever generals.

If you've ever played the Advance Wars saga, gameplay in Commander Wars will be familiar to you. Your objective at the beginning of each game is to capture the closest buildings, which will provide you with resources. With these resources, you can recruit more and more troops, which you can use to capture more land while also attacking your enemies.

The battles between troops follow the same mode as in the aforementioned Advance Wars. The success or failure of your attacks depends on several factors, including the position of your units (for example, if they're on higher ground, they'll be more effective) and their type (for example, mortars are especially effective against tanks). If you don't take all these factors into account, you'll give the enemy an advantage.

Commander Wars is an excellent adaptation of one of the most beloved turn-based strategy sagas. The game is also free and open source, has mod support, and is still in active development.
