How the Game Plays

Outerspace Invaders by Pearfiction is a narrative-driven slot that transports players to a 1950s suburban setting under siege by extraterrestrials. The game follows the story of Rachel Page, a resourceful heroine on a mission to rescue her fiancé, Robert, from the clutches of the alien overlord Zerk. The base game is played on a standard 5x3 grid where symbols include retro-styled characters and high-tech weaponry. Winning combinations are formed by landing three or more matching symbols across the 25 fixed paylines, starting from the leftmost reel. A key feature in the base game is the Rachel Expanding Wild; whenever Rachel appears on the central reels and can contribute to a win, she expands to cover the entire reel, significantly boosting payout potential.

Rachel's Revenge Free Spins Explained

Triggered by landing three or more Zerk scatter symbols, this feature is the centerpiece of the game's combat-heavy narrative. Uniquely, the grid shifts from a five-reel layout to a four-reel configuration for the duration of the round. This feature functions as a "Boss Battle" where Rachel faces off against Zerk. Special attack symbols appear on the reels; as Rachel lands shots with her shotgun or explosives, she depletes Zerk’s health bar. If the player manages to defeat the alien leader, Robert is rescued, and a win multiplier of up to 10x is applied to the total feature winnings.

Radar Shootout Bonus Explained

The Radar Shootout is a pick-me style bonus game activated by three or more Bonus symbols. The screen transitions to a retro radar display filled with incoming flying saucers. Players select targets to destroy, revealing instant cash multipliers. This arcade-inspired round continues until a "Game Over" message appears, with the potential to win up to 250x the stake depending on the number of symbols used to trigger the entry.
