NetEnt has many slots with a space theme, but Aliens is a slot machine that shows you the world of the extra-terrestrial creatures, how they look, what they do, and how scary they are. The aliens present in this video slot are destroyers and highly dangerous creatures, so we can say that the theme also includes some horror elements. Aliens slot is a rather complex game, with many rules and special features, but also some major chances for great wins.

An Unearthly Setting

Even though Aliens features a theme similar to Microgaming’s Cosmic Invaders, it is nothing like it. As you load the game, you will see a vacant planet in the background, and dust flying as the wind blows. On the reels, you will see several scary-looking aliens, in different forms and shapes and in different colours. The Wild is the symbol that reads Weyland-Yutani Corp which can appear on reels 2 through 5 in Level 1 and randomly anywhere on the reels during Level 2, with the exception of the Ammo Clip Reel. The Wild substitutes for all symbols, except for the Multipliers in Level 2.

Aliens’ Mission: Seek and Destroy

You’ve been reading about Levels 1 and 2, but what are they actually? Well, at the top of the reel set, you will see an Alien Activity Meter with a total of 9 steps. As you go through Level 1 and form wins, all the winning symbols except for the Wilds transfer to the meter and increase the 2x Multiplier by the number of symbols you collect by +1. If you form no wins during the spin, the Multiplier decreases by 1. But, if the meter reaches step 9 you go straight to Level 2.

In Level 2, you get all Multipliers from Level 1. During Level 2 you need to fight to reach Queen Hive. This level features an Ammo Clip reel with Ammo symbols, a pulse rifle, an Ammo Clip Counter, and the Alien Activity meter with 10 steps that will take you to Level 3. On the first spin in Level 2 of Aliens’ gameplay, 3 of the lowest-paying symbols go to the centre of reels 1, 2, and 3 and activate a bet line win. Then, the Ammo Clip appears with the Clip Counter that contains 1 Ammo Clip. The Ammo Clip Counter increases by +2 with Ammo symbols appearing in a centre position and activate the Re-Spins.

As you complete the meter in Level 2, you get to Level 3 where you shoot the Alien and destroy the Hive. This level features a Smartgun and at the start, you get 4 Ammo Clips and 5 bonus Re-Spins. But you also have 2 reels, a Grenade Multiplier, and a Strength Reel full of grenades here. The Strength Reel stops and the Multiplier follows, and you throw a grenade to the Queen Hive, defending the Marine with 1 Ammo Clip. As you cause damage to the Queen, you multiply the damage by 1x to 10x. When the Hive Health Meter reaches 0, the Queen dies and you get 240x the bet payout.

Win Out of this World Payouts

Aliens slot gives you a betting range that goes from 0.15 to 150 credits. NetEnt promises 570,000 coins maximum payout, so playing Aliens slot for real money can be quite rewarding. Our review shows that Aliens is a big win video game that can keep you entertained for a long time with the bonus game options, so find the best casino you can and load it. It offers a solid 96.4% RTP and it gives some major rewards. Join in on the Aliens’ mission and have fun!
