Brute Force Alien Onslaught Slot (Nolimit City)

The Brute Force Alien Onslaught slot is played on 6 reels, 5 rows and 30 fixed paylines. Winning combinations are formed when you see 3 or more matching symbols from left to right, starting from the leftmost reel, and across any of the 30 paylines. As expected, only the highest win per payline is awarded.

Bets-wise, the minimum bet per spin is 20p. With up to £5 bet limits (due to UK regulation), use the ‘Coins’ icon to see all available stake options. Players outside the UK can opt for Autoplay (up to 1,000 auto spins) and Turbo/Quick Mode.

The Brute Force Alien Onslaught RTP rate is 96.01%: 53.03% is from the base game with 42.98% from the bonus features. As with other Nolimit slots, there are alternative RTP settings: 95.35%, 94.07% and 92.04% (look in the Paytable to determine which RTP you’re playing with). The demo version above uses the highest RTP rate.

Extremely volatile (10/10), the hit frequency rate is 21.28%: this means a winning combination will land every 4.7 spins, on average. When it comes to triggering the free spins (there are 5 actually), it will take approximately 274 spins (again, on average).

Brute Force Alien Onslaught slot benefits from 80,000 x bet max wins. Known as ‘Game Breaker’, the max win probability is 1 in 102 million spins. For context, winning 100 times your total bet or higher will occur every 1 in 698 spins.

With an alien/space theme, the Brute Force Alien Onslaught slot is the sequel to Brute Force (released in October 2024). In this instalment, the squad of unruly heroes defeated Hyper but now face a new threat in Xylox: a planetary overlord who wants to exterminate the human race once and for all. Joshua and Jason has enlisted the help of fearless mercenary Jade.

Like the original game, it does have an arcade/video game feel. Using 8-bit graphics, the mesmerising synthesizer-style soundtrack suits the visuals perfectly.

On the reels, there are low-value A, K, Q, J and 10 royals. The higher-value symbols include 5 different aliens with the best-paying symbol awarding 24 x your total bet for 6 in combination. Look out for the Wild symbol as it substitutes for all paying symbols: it also randomly transforms all low-value symbols into mid-paying symbols.

Brute Force Alien Onslaught also benefits from several special symbols: 4 types of xNudge Wilds as well as Red and Blue Scatters. More on their functions below.

Brute Force Alien Onslaught Mobile

With HTML5 used for all Nolimit City games, Brute Force Alien Onslaught can be played on mobile, desktop and tablet devices. Compatible with iOS and Android smartphones, Portrait Mode is used so it occupies more of your vertical screen setup.

The Brute Force Alien Onslaught slot focuses on xNudge Wilds with the Xylox xNudge Wild collecting multiplier values from the other 3. With 5 free spins features, you benefit from sticky xNudge Wilds for an unrelenting onslaught.

xNudge Wilds

Brute Force Alien Onslaught comes with 4 types of xNudge Wilds. Landing fully stacked and always nudging to be fully visible on the reels, random multiplier values update at the the bottom for Joshua, Jason and Jade xNudge Wilds.

When it comes to the Xylox xNudge Wild, it combines the multiplier value of all other xNudge Wilds and adds that number to itself. However, xNudge Wilds do have different nudge multiplier values:

• Joshua xNudge Wild: Each nudge increases the win multiplier value by 1 with the maximum multiplier value 7x.
• Jason xNudge Wild: Each nudge increases the win multiplier value by 2 with the maximum multiplier value 15x.
• Jade xNudge Wild: Each nudge increases the win multiplier value by 5 with the maximum multiplier value 40x.
• Xylox xNudge Wild: Each nudge increases the win multiplier by 1. When landing for the first time, it collects multiplier values from Joshua, Jason and Jade xNudge Wilds. If it becomes sticky, it continues to collect multiplier values from other xNudge Wilds. Another +1 increase is award once the nudge is complete.

To keep on top of things, there is an xNudge Meter which summarises the overall xNudge multiplier values on the winning symbols.

Brute Force Alien Onslaught Slot

Rating: 4.6/5

Brute Force Alien Onslaught takes the original slot to a whole different dimension with more xNudge Wilds, more free spins features and double the max win potential (80,000 x bet).

Chris Taylor

Like its predecessor, the Brute Force Alien Onslaught slot focuses on xNudge Wilds. Bigger and badder than the original game, the graphics are almost identical which helps keep the story going.

In the base game, there are 4 different xNudge Wilds as opposed to 3 in the original. Even though the maximum multiplier values are lower in Brute Force Alien Onslaught, the addition is the Xylox xNudge Wild is worth noting: it collects multiplier values from the other xNudge Wilds and can be become sticky, which sees it continue to collect multiplier values.

Then you have the 5 free spins features (with the original game only offering 2). Nolimit City has ramped things up with sticky xNudge Wilds! The Stellar Punishment Spins feature is potentially the most lucrative as Jade xNudge Wilds may become sticky and Xylox xNudge Wild always becoming sticky.

With subtle additions, Nolimit City has managed to the Brute Force Alien Onslaught slot a much better proposition than its predecessor. This is evident in the 80,000 x bet max win potential which is double that of the first outing. Overall, I think NLC has produced another cracking sequel which will be pretty hard to top.

If you fancy try slot game sequels, my guide to the top 10 includes Nolimit City’s Tombstone Slaughter, San Quentin 2: Death Row and Mental 2 as well as Relax Gaming’s Money Train 4. After more alien battles and adventures? Check out my guide to the best space-themed slots.
