In G-Tok: The Defender The user assumes the role of the pilot of the spacecraft, which enters the battle with alien invaders. Hostile creatures intend to capture the galaxy, and therefore begin a full -scale invasion. The player’s task is to prevent them, destroying everyone who stands in the way.

The main emphasis in G-Tok: The Defender is made on the gameplay. All battles take place at high speeds, and it is important for the gamer to constantly monitor what is happening on the screen. This happens at each level regardless of the number of enemies. Throughout the entire plot campaign, the complexity of the clashes will increase. This applies not only to the number of enemies, but also their behavior (movements will become more meaningful, ships will become less substituted under a straight fire). In addition, the character will have the opportunity to improve his aircraft, gaining access to new weapons (blasters, guns, machine guns, etc.). The locations on which contractions occur are also changing, but this is displayed only in minor landscape adjustments. Due to the fact that everything happens in the sky, this will not affect the gameplay in any way. It was not without clashes with bosses, where each time it will have to be invented by a new tactic, trying to calculate the weak point of the enemy.
