A free strategy game, from tribes to the stars

In ÈRES - War of the Ages, two strongholds face one another. Recruit units that advance and fight automatically, build turrets and choose when to evolve your civilisation.

Advance through five ages: Wild Dawn, Kingdoms of Bronze, Crowns of Iron, Cities of Steam and Stellar Horizon. Build your army from fifteen units spanning melee, ranged and heavy roles.

Explore the battlefield

Fog of war hides unexplored areas. Advance your units or send aerial scouts to locate the enemy stronghold. Explored terrain stays on your map; drag with your mouse or finger to move the camera.

Single-player campaign and skirmishes

The campaign features six battles. Skirmishes offer three difficulty levels and two formats: long or quick. Long matches have no time limit; the simulation speeds up after five minutes. Quick matches start at ×2 speed and strongholds begin taking attrition damage after five minutes. Your single-player progress is saved on your device.

Meet Ysko in the Guide

Before you play

How do I create an account?

Open the player profile. You can sign in with Google, Facebook or Discord, or create an email account and follow the verification link you receive. Available options are shown in the game.

Where can I find my previous solo save?

The current version uses the ÈRES Arena address. Previous local saves on the studio website are neither erased nor automatically transferred. Open the previous solo version 1.7.1.

Do I need to install ÈRES?

No. Click “Play ÈRES” to load version 1.21.0 in your browser. You can try solo play without an account and create one from the player profile to access your profile and rankings.

How do I play on my phone?

Is my progress saved?

Solo progress remains saved in the browser on this device and for the game address you use. A player account provides your profile and online features; it should not be confused with automatic syncing of the entire solo campaign.
