In Stba.io (Tactics Core), choose your battleship from a wide range of powerful units and enter the battlefield. Start the game by choosing a basic unit such as tanks, bombers, fighter jets, Javelin (artillery) or Manta (air fighter) with different attack types. Increase your kill count to unlock more advanced units like Harpy and Gladiator. Become even more lethal to unlock super units like the massive flying battleship and the Ion Cannon!

Each team starts with a limited number of respawn chances. When you kill an enemy unit, a new enemy unit replaces it and the spawn count for the enemy team decreases. When the spawn count reaches 0, all base defenses may explode, leaving the Command Center defenseless. Work as a team to destroy the enemy Command Center before the enemies destroy you!

Stba.io game membership offers a free membership system, allowing players to register their names and access the secret features of the ships. Stba.io stands for “Strike Tactics Battle Arena” and RTS is the official title of the program called “Strike Tactics”.

Try to survive to level up so you can jump to higher levels. When you reach enough kills, switch to stronger units so you will be extra stronger against enemies. Don't forget to use your special abilities against enemies, these abilities are usually located in the middle of the bottom of the screen.

It is important to use the small map in the Stba.io game effectively because your warships have a radar system and allow you to see the location of the enemies. Keep an eye on the health of your Command Center by looking at the bars at the top of the screen. If your team runs out of spawns, head back to your Command Center and defend!
