Like any good game based on battles and war, there ought to be some decent special features included alongside. Silent Run does not disappoint in this area, offering up a nice selection of these. This starts with the wild symbol, which is represented by the red flashing light. As a wild icon, this will stand in for any other on the reels in order to form a win, with the exception of both the echo bonus icon and the echo wild symbol. And speaking of the echo wild, this is the red-coloured sonar screen. Should this appear anywhere on reel three, it will send out three sonar signals to search the area for hidden wild icons. If it finds any, they’ll transform and have the possibility of forming extra wins.

As far as the echo bonus symbol goes, this is represented by the green sonar screen, and if this appears anywhere on reel three, it will trigger the game’s bonus round. Firstly, it will send out three sonar signals to search the reels for torpedoes. The number of these that are located will be a random amount between two and five. This is how many of this weapon you’ll have for the bonus game, which sees you take aim at enemy ships! Simply select a ship to fire at, take aim and release the torpedoes. As you watch the ships explode upon impact, a different amount of coins is won. Your win will be multiplied by the multiplier that is attached to each torpedo as well, and this multiplier increases after every hit until your arsenal has run out.
