Earning XP

However, to win each round, end up shooting the most enemy ships in this intense space warfare and you will be the topmost player on the leaderboard.

Playing Environment

Additionally, the in-game screen is also intuitive: The in-game screen shows both teams’ scores at the top, a leaderboard, a weapons vault, and the player’s score bar. The player can take their spaceship in any direction, but only within the defined lines within the space.

Graphics

The game offers a high-quality and techy 2D graphical interface, just the perfect blend for a space warfare game.

The player should pay heed to that as the health bar decreases quickly upon intense attack.
