Brute Force: Alien Onslaught: story and setting
After defeating Hyper and his swarm in the first game, a new threat enters Earth’s atmosphere. Xylox, a planetary overlord, wants to wipe out humanity for good. Joshua and Jason recruit Jade, a fearless mercenary who doesn’t know defeat, and the Brute Force reassembles.
The mechanics follow the story closely. Each of the three heroes and Xylox is an xNudge Wild with its own rules. The mix of red and blue scatters decides which of five bonuses you get.
How it plays, summarised from the studio’s description
- Four xNudge Wilds
- They land stacked and always nudge until fully visible. Each nudge adds +1 for Joshua (up to 7x), +2 for Jason (up to 15x) and +5 for Jade (up to 40x). Xylox collects the other Wilds’ multipliers into its own.
- Wilds
- A Wild turns every low-paying symbol on its reel into a mid-paying symbol.
- REDemption and Super REDemption
- Three scatters with at least two red give 10 spins; four with at least three red give 10 super spins. A Xylox Wild always sticks when it lands.
- BLU Genesis and Super BLU Genesis
- Three scatters with at least two blue give 10 spins; four with at least three blue give 10 super spins. The super version guarantees a sticky Joshua Wild on the first spin.
- Stellar Punishment
- Two red plus two blue scatters give 10 spins. A sticky Jade Wild lands on the first spin, and Joshua and Jason never appear.
- Game Breaker
- If the total win passes 80,000x, the round ends and 80,000x is paid.
The RTP split and frequencies the studio publishes
| Item | Value | What it means |
|---|---|---|
| Total RTP | 96.01% | In theory, 96.01 back for every 100 staked over the long run |
| Base-game share | 53.03 | What base spins return without any bonus (55% of the total RTP) |
| Bonus share | 42.98 | 45% of the total RTP (the largest bonus share of the four Nolimit City games here) |
| Hit rate | 21.28% | A win roughly once every 4.7 spins, including wins below the stake |
| 100x+ wins | once every 698 spins | about every 12 minutes at one spin a second |
| Free spins | once every 274 spins | about every 4.6 minutes at one spin a second; in between, only the base-game share (53.03 points) comes back |
| Max win | 80,000x, once every 102,000,000 spins | about 3.2 years on average at one spin a second |
| Volatility | INSANE (31.61) | INSANE (the 2nd highest index of the five Nolimit City games here, Mental II included) |
| Expected loss, KRW 1,000 × 1,000 spins | KRW 39,900 | 3.99% of KRW 1,000,000 staked (the house edge) |
What Nolimit Boosters and Bonuses cost and guarantee
| Option | Type | Cost (x base bet) | At a KRW 1,000 base bet | What it guarantees (studio description) |
|---|---|---|---|---|
| xBoost | Booster (per spin) | 4.6x | KRW 4,600 | A scatter on reel 2 (free spins 8x more likely) |
| Super xBoost | Booster (per spin) | 32x | KRW 32,000 | Scatters on reels 2 and 3 (free spins 54x more likely) |
| 1 Guaranteed xNudge® xBoost | Booster (per spin) | 40x | KRW 40,000 | At least 1 xNudge Wild |
| 2 Guaranteed xNudge® xBoost | Booster (per spin) | 220x | KRW 220,000 | At least 2 xNudge Wilds |
| 3 Guaranteed xNudge® xBoost | Booster (per spin) | 750x | KRW 750,000 | At least 3 xNudge Wilds |
| 4 Guaranteed xNudge® xBoost | Booster (per spin) | 2,500x | KRW 2,500,000 | At least 4 xNudge Wilds |
| 5 Guaranteed xNudge® xBoost | Booster (per spin) | 8,000x | KRW 8,000,000 | At least 5 xNudge Wilds |
The game page gives no RTP per option, so no per-option expected loss is calculated. The cost is certain: the priciest, 5 Guaranteed xNudge® xBoost, is KRW 8,000,000 a time at a KRW 1,000 base bet.
The chance of each event and the expected loss over 100, 1,000 and 10,000 spins of Brute Force: Alien Onslaught

Worked out from the studio’s published average frequencies as 1 − (1 − 1/frequency)^spins. It treats spins as independent; real sessions swing widely around these figures.
Reading the numbers
- Of the 96.01% RTP, only 53.03 points come from the base game and 42.98 from the bonus, the heaviest bonus reliance of the Nolimit City games here.
- The studio says xBoost (4.6x) makes free spins 8 times more likely and Super xBoost (32x) 54 times. Applied to the base 1 in 274, that is roughly 1 in 34 and 1 in 5 (our arithmetic).
- The priciest option, five guaranteed xNudge Wilds, costs 8,000x the base bet, or KRW 8 million at a KRW 1,000 stake.
- Its volatility figure is 31.61, rated INSANE. Wins of 100x or more come most often of the four, about once in 698 spins, yet the max win is very rare at 1 in 102,000,000.
