There are three stages in the game just as there are in the film: First up you’ll search for Alien activity and collect symbols with multiplier values which are added to the Alien Activity Meter. Once you complete the 9 steps you will move on to Level 2.
Here, you’re given a guaranteed win on your first spin, after which you’ll be bombarded from all sides by a massive Alien attack before you reach the Queen Hive. Any multipliers collected from the first stage apply here; play it right and you can get a nice six times multiplier on three symbols per spin.
Make sure you use the Ammo Clip Reel. The symbols in here show up on the middle position of a reel and will boost the Ammo Clip Counter to trigger re-spins. The counter goes down after every re-spin as Aliens are being shot.
Finally, you’ll play the all-important Level 3: In The Hive you get 5 re-spins. Completing each step on the Hive Health Meter will get you closer to killing the Queen and destroying the hive which will give you a massive 240 times your stake cash prize! There is no guarantee you will kill the Queen though so look out for the multiplier on the middle position of the multiplier reel as this can boost the damage done by up to 10 times.
