About the Game

If you have been searching for a real-time strategy game that respects your intelligence and your time, RTS Siege Up! - Medieval War is worth your attention. Developed by ABUKSIGUN as an actively maintained indie project, it strips away the monetization clutter that plagues most mobile strategy titles and replaces it with genuine gameplay depth. There are no pay-to-win mechanics, no artificial timers throttling your progress, and no booster bundles to purchase. Matches typically run between 10 and 20 minutes, which keeps sessions focused without sacrificing the strategic weight that RTS fans expect.
The single-player campaign spans 26 missions, each designed to introduce or challenge different mechanics rather than repeating the same formula with larger numbers. You will manage resource economies, construct defenses, plan offensive pushes, and adapt to scenarios that shift the rules underneath you. The campaign is not a tutorial stretched thin but a proper progression that builds your understanding of the game's systems over time.
Multiplayer is where the community dimension opens up. The game connects players through Wi-Fi or public servers and supports several modes of play:
PvP and PvE matches with optional bot opponents
Team play with unit sharing between teammates
Spectator mode for watching live matches
In-game chat and reconnection support
Cross-play between mobile and PC platforms
Beyond standard matchmaking, an in-game community library holds more than 4,000 maps created and shared by players. You can browse, download, and rate missions made by others, or upload your own creations for the community to discover.
Building those custom missions is handled through a built-in level editor that goes well beyond basic map drawing. Creators can script dialogue, set up triggers, and design gameplay scenarios that approach the complexity of visual scripting tools. This makes it possible to build full campaign-style missions with narrative elements, not just blank skirmish maps.
On the battlefield, the unit roster covers the core pillars of medieval warfare. Infantry fighters, archers, and cavalry each have distinct roles, and naval combat adds another dimension with battle ships, transport vessels, and fishing boats supporting operations across water. Walls made of stone or wood can only be destroyed by siege weapons such as catapults, which means attackers must bring the right tools and defenders have a genuine structural advantage to work with.
Other systems that contribute to the overall experience include:
Autosave functionality and optional replay recording
Control groups and minimap support for army management
Resource capturing and strategic position control across the map
Full portrait orientation support for smartphone play
Classic RTS cheat codes, toggleable in settings
Experimental peer-to-peer internet play and cross-platform modding support
The developer remains active and reachable through Discord and social channels, with direct feedback from players shaping ongoing updates. For anyone who wants a medieval RTS that earns your victories rather than selling them, RTS Siege Up! - Medieval War delivers a complete and honest package.
