GoldenGBA by 3DSage is a survival shooter game made for the Game Boy Advance.
The game is made into a four player split screen where you compete against three computer-controlled enemies. Carefully watch the screen because it’s the part of the strategy where you can peak at another’s viewport. Kill three players to win the game. If you can see an enemy, they will slowly turn towards you and lock on and fire. If you fire at them, when they can’t see you, they will turn towards you and fire. If they can see you even if you aren’t looking at them, they will lock on and fire. When anyone dies, they will respawn in a new random unoccupied location.
