The 2024 original slot put two mercenaries against Hyper with three nudging Wilds and a 40,000x limit on the round. Brute Force: Alien Onslaught doubles that limit to 80,000x, drops Jade into the third Wild slot, then adds a fourth Wild that exists to take what the other three have built. Xylox is both the villain of the story and the strongest symbol on the reels. The second change is structural. This is a 30-line slot on a 6×5 board, from a studio that nearly always counts ways instead.
Joshua, Jason, and Jade each build their own multiplier as they nudge into full view. Xylox does not have to. The first time it lands, it collects the multiplier values carried by the other three and adds them to its own total, so a board already showing a 7x, a 15x, and a 40x transfers all three into one symbol. If Xylox turns sticky, the collection keeps running. Any non-sticky Joshua, Jason, or Jade landing afterwards is emptied into it before the round finishes, which is why the xNudge Meter can climb long after the Wild that started it has gone.
A second rule fires whenever any Wild appears. The Wild randomly converts the low-paying symbols on its reel into mid-paying ones, so card ranks worth 2.5x at full length become aliens worth 6x or 12x. On 30 fixed lines, that lands harder than it would on a ways engine, because every line crossing that reel is upgraded at the same time. The art keeps the studio’s sci-fi register in comic-book colour, five aliens in red, yellow, blue, pink, and green over gold card ranks.
Scatters land in red and blue, and the colour split decides which of five rounds opens. All five run 10 spins, so the difference is in which Wilds can appear and which of them stick. Three Scatters including two red gives REDemption Spins, where Joshua stays out of the reel set and Xylox sticks whenever it lands. Three including two blue gives BLU Genesis Spins, and there Joshua, Jason, and Jade can all turn sticky. The counts are what you watch for on a 6×5 grid, because two Scatters of one colour do nothing on their own.
Four Scatters including three red gives Super REDemption Spins, with both Joshua and Jason held back. Four including three blue gives Super BLU Genesis Spins, which opens with a sticky Joshua from the opening spin that never leaves. Two red beside two blue gives Stellar Punishment Spins, where a sticky Jade opens the round and Joshua and Jason are absent again. Xylox is sticky on landing in all five.
Seven Booster settings run beside the stake, and each one charges its own cost per spin. xBoost 1 is 4.6x the stake and fixes a Scatter onto reel 2; xBoost 2 is 32x and fixes two, on reels 2 and 3. Above those, five Guaranteed xNudge settings at 40x, 220x, 750x, 2,500x, and 8,000x the stake fix a minimum of one, two, three, four, or five xNudge Wilds on the spin. The step from 750x to 8,000x buys two more guaranteed Wilds, which is the sharpest jump on the ladder. Symbol pays are the same with a Booster running as without one.
Each xNudge Wild lands stacked and nudges until it stands fully in view, and the step it takes on the way is what separates the four. Joshua climbs by 1 a nudge and tops out at 7x. Jason goes up by 2 to a 15x limit. Jade jumps 5 at a time as far as 40x. Xylox adds 1 per nudge, plus whatever it has taken from the other three, and picks up another 1 once the nudge is complete. The xNudge Meter below the reels totals the multiplier values riding on the winning symbols, so the number you read there is the combined figure rather than any single Wild’s.
Wins pay across 30 fixed lines, not ways. A matching run has to start on the first reel and carry on across touching reels, and three symbols is the shortest run that pays anything. A thumb never has to travel far here, with the stake ladder, the Booster bolt, and the information panel all within reach of where a hand already holds a phone. Free play runs in the browser, the same way as the studio’s other titles on the site, Soaked by Seamen among them.
The demo takes bets from €0.20, with the top end at €100. The RTP in free play is 96.01%. The studio’s own volatility label for this one reads Extreme and High is as far as our scale reaches, so the two land as close together as they can get. 30 fixed lines on a five-row board, with nothing paying under three symbols, is what earns the label.
Five card ranks share one set of figures, the two mid aliens share another, and only the red-eyed alien pulls away from the group. Six of a kind is a full line on a 6-reel board, and the Wild pays 24x at that length as well. Nothing under three matching symbols registers, which is why the 0.2x on the ranks is the smallest figure in the table.
| Symbol | 3 | 4 | 5 | 6 |
|---|---|---|---|---|
| Red-eyed alien | 2x | 5x | 11x | 24x |
| Yellow hound alien | 1x | 2.5x | 6x | 12x |
| Blue alien | 1x | 2.5x | 6x | 12x |
| Pink-mawed alien | 0.5x | 1.5x | 3x | 6x |
| Green spider alien | 0.5x | 1.5x | 3x | 6x |
| A, K, Q, J, 10 | 0.2x | 0.5x | 1.2x | 2.5x |
| xNudge Wild | 24x |
Sequels that only lift the cap are easy to ignore. This one rebuilt the Wild set instead, and Xylox collecting from Joshua, Jason, and Jade is the cleanest escalation the xNudge family has been given. Thirty fixed lines make the waiting real and the best symbol reaches only 24x, so the five rounds carry the game. For a player who wants the multiplier maths on show, it delivers.
Xylox is the decision everything else on this game answers to. Three Wilds that each build a multiplier of their own is a familiar Nolimit City arrangement; a fourth that empties the first three into itself is not. It changes what a good screen looks like, because the value of a 40x Jade is no longer the 40x, it is what Xylox can do with that 40x if it arrives while the Jade is still loose. Sticky Xylox is the version that pays, and all five rounds make it sticky on landing.
The lines format is the other departure. Thirty fixed lines on a 6×5 grid offers 30 chances a spin whereas a ways engine would count hundreds, and the paytable is built to match. A 24x top pay for six of the red-eyed alien is tall next to the 2x and 3x tops the studio hands most of its releases, and card ranks flattening at 2.5x keep the floor low enough that the multipliers still have to do the work.
The trade shows up quickly in free play. Fixed lines pay less often than ways across the same board, one symbol carries the tall pay, and Xylox is worth nothing until Joshua, Jason, or Jade has built something for it to take. A round where Xylox lands first is a round where it collects a 1x and waits. The Booster ladder answers that, since the Guaranteed xNudge settings put the Wilds on the board instead of leaving them to chance, though the cost per spin climbs steeply the higher you go.
Reviewed beside the rest of the studio’s 2025 output, this is a sequel that changed its maths rather than its skin, and the result reads clearly for a Nolimit City release: four Wilds, five rounds, one villain that collects. Players who want frequent returns should look elsewhere on the studio’s shelf, but anyone who has watched an xNudge meter climb will recognise what the fourth Wild is for.
