Raider is a retro jump'n'run game throughout. It is controlled with the "arrow keys" and you use "A" to jump and "S" to use the dagger. The gun can be used using the "D". In some areas you can jump with the "arrow key down" and "A". Signs can be read by using the "arrow up" when you stand in front of it. The music and the whole gameplay is also very retro-heavy. So lean back and feel back in the good old days when games were pure games.
