Free-to-play principles in Xterium

Six rules governing Xterium monetization.

No trial periods

No "30 days free then subscription". Game fully available from day one, forever.

No pay-to-win

Premium is convenience, not power. Combat stats are identical for paying and free players.

All 3 universes free

War of Alliances, Classic, Reborn — all accessible without payment. One login, all three worlds.

Premium is convenience, not power

Combat stats are identical for paying and free players: subscription and boosters save time — they do not buy victory.

Mobile apps free

iOS and Android — no in-app purchases, no ads, no watermark. Installed from store — play.

Transparent economy

Everything premium offers — described openly on the tariff page. No hidden advantages, no "secret boosts".

Frequently asked questions about free-to-play

What exactly is free?

Everything: registration, access to all three universes, mobile apps, core gameplay, guides, forum, alliance communication. No trial period and no mandatory subscription.

Is there pay-to-win?

No. This is a central principle. Premium account gives convenience (long build queues, extra filters, advanced stats) but no combat advantage. All strategies and victories are achievable without premium.

What does premium give?

Build queues hours ahead, advanced espionage, advanced galaxy filters, design themes. Subscription from ~$5/month, applies to all universes. No combat bonuses.

Can I play at top level without donating?

Yes. Most top alliances are a mix: some with premium, some without. Victory is decided by strategy, coordination and time — not money.

Are there ads inside the game?

No in-game ads. No banners, no "watch 30 sec video — get resources". We earn only from premium subscriptions.

Is the game monetized any other way?

Money buys the VIP subscription, boosters and premium resources. They cut the waiting, not your combat strength — paying does not win battles. Plus cosmetics and tournament sponsor bonuses.
