**Summary:**

The US Steam deal cuts Infernax to $9.99, with local co-op and branching endings in a demanding pixel-art adventure.

**Infernax is $9.99 on the US Steam store**, down 50% from $19.99. Steam lists November 18 as the offer’s end date, without an exact cutoff time in the displayed offer. This is a paid Windows PC game purchase, not a free weekend or subscription benefit.

## The deal at a glance

## A cursed kingdom, with choices that matter

Berzerk Studio’s side-scrolling action adventure follows Alcedor, a knight returning to a homeland overrun by monsters. Its appeal is the combination of difficult castle encounters and exploration: new equipment, skills and stat upgrades support a journey through hidden areas, while decisions influence later consequences and endings.

That makes this a different proposition from a straightforward arcade run. Players who enjoy revisiting routes, searching for secrets and committing to a character build have more to weigh than the discount alone. The publisher emphasizes a demanding challenge, and the grotesque pixel-art monsters and blood make it a poor fit for anyone seeking gentle, family-friendly fantasy.

## What co-op includes

The existing Deux or Die update adds Cervul the Squire alongside Alcedor for local co-op. Solo players can also use a hot-swap mode. This is an established feature, not a newly announced expansion or an extra purchase required for this deal.

Steam lists shared/split-screen co-op and Remote Play Together. At the check, its English-language review summary was **Very Positive across 1,106 reviews**; the smaller recent-review group was Mostly Positive across 14 reviews. These are dated storefront snapshots, not a promise that every player will enjoy the difficulty.
