Three levels form the free portion of Boltgun Boom. Players can download the game and play that opening section before deciding whether to unlock the full experience through an in-app purchase.

Optional purchases exist, but Nitro Games explicitly says the game has no advertising and no energy mechanics. Free installation therefore should not be confused with a conventional free-to-play structure; the initial download effectively functions as a trial.

A fast FPS has an obvious touchscreen problem to solve

Moving a boomer shooter onto a phone involves more than reducing the image to a smaller display. Boltgun depends on rapid movement, aiming and immediate enemy recognition, while touch controls have to share the same surface as the action itself.

Nitro Games says Boltgun Boom has mobile-optimized controls and gameplay systems. The company does not provide measurements that would allow independent conclusions about input precision or latency, so the adaptation work can be confirmed without pretending its execution has already been tested here.

The released version retains a single-player campaign structure across multiple worlds, with hidden routes and secrets alongside cultists, traitors, daemons and large war machines.

Its monetization avoids two familiar mobile mechanics

The absence of an energy system means the official design does not impose a refill timer between play sessions. The lack of advertising removes another common way of monetizing a free download.

That does not make Boltgun Boom a free game. It moves the purchase decision until after a small playable sample, which is why Nitro Games describes the model as free-to-try.

This is also why the word “premium” in the marketing needs a little context. The application itself can be downloaded at no initial cost even though access to the full game is sold through an in-app unlock.

This is a dedicated mobile adaptation, not the console sequel

Nitro Games is not developing the original Boltgun or its mainline sequel. The Finnish studio licensed Warhammer 40,000 from Games Workshop to build a mobile adaptation of the shooter series originally developed by Auroch Digital.

Nitro Games announced availability on iOS and Android across major markets on September 23. Google Play now exposes the installable product in supported regions and describes the free opening levels directly in the store listing.

For a shooter deliberately styled after the 1990s, its payment structure may be nearly as retro as its pixels: try part of the game, then buy access to the rest.
