BC4000 iOS Game

BC4000 - Civilization Model is a turn-based 4X strategy game for iOS (iPhone and iPad). It is a mobile homage to classic Sid Meier's Civilization games (especially Civ II & Civ V), with deep empire-building mechanics.

Core Gameplay

Start in 4000 BC with a settler and guide a civilization from the Stone Age through to the Space Age (up to ~AD 2100).
Classic 4X elements: Explore the world map, Expand by founding cities, Exploit resources through improvements (irrigation, mining, etc.), and Exterminate rivals.
Key systems include technology research, city management (buildings, production, workers), diplomacy & trade, military units and combat, wonders, culture/faith/gold balance, and government types.
Victory conditions: Domination (conquer all rivals) or Space Race (reach Alpha Centauri).

Features

Multiple modes: Single-player, hot-seat (pass-and-play), and online multiplayer.
Various rulesets and customizations (including Civ V-inspired, sandbox, and others added over time).
Fully offline play (no account required).
Map editing, mod-like custom tilesets, VoiceOver accessibility support, and regular updates with performance tweaks, new content, and bug fixes.
Designed especially for iPad, with iPhone support (including portrait/landscape options in later updates).

Details

Free with in-app purchases (e.g., subscriptions for unlimited funds or ad removal/premium features).
App size: ~170–200 MB.
Requires iOS 12.0+.
Age rating: 9+.
Actively updated (recent versions added new rulesets, UI improvements, massive Earth maps, etc.).

Overall

BC4000 is an excellent choice for fans of deep, single-player or multiplayer turn-based strategy who want a Civilization-like experience on iOS devices.
