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 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.

Over 1,000 spins there is a 2.6% chance of never reaching free spins. The chance of the max win in the same 1,000 spins is 0.00098%, against an expected loss of KRW 39,900.

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.
