Allied Generals Shattered Alliance (AGSA) is a total conversion modification for Red Alert 2 - Yuri's Revenge using Ares - A Yuri's Revenge Expansion DLL.

What if the European states had become a superpower after the defeat of the Soviet Union?

What if China had rose to power and expanded its influence in the Far East?

What if the USA had been thrown into chaos by a devastating world event and for an uprising to bring unity to a neglected populace in the Middle East?

With an uneasy stalemate between the European Self Defence Force (ESDF) People's Republic of Asia (PRA) and the mysterious Paradigm, the only outcome is war.

"There is no avoiding war; it can only be postponed to the advantage of others" - Niccolo Machiavelli

Since Shattered Alliance (SA) is a total conversion modification, gameplay mechanics in terms of scale, playstyles and unit use, differ greatly from the original game.

I would say a lot of RTS are focused a bit too much on "rushing" and micromanagement. It always tends to be, you must go this build order and spam one or two units and if you don't, one mistake will cripple your base. On the opposite extreme, there is a lot of RTS which suffer from stalemates because turtling is safer than attacking.

My own personal preferences for RTS, are epic battles which consist of armies with a diverse range of units. You're rewarded for expanding and aggressive gameplay. With that explanation out of the way, lets move on. From internal beta testing, the average game in Shattered Alliance lasts between 45 minutes to 1 hour, with some lasting 2 hours or more. If you're looking for RA2 gameplay, I would recommend the numerous other mods posted on ModDB but if you're interested in a different approach, read on.

Note: Graphics and mechanics are WIP, subject to change.

urban combat


The majority of infantry in Shattered Alliance can garrison civilian structures in SA, the exceptions being engineers, infiltrator infantry e.g. spy type units and heros. Whilst garrisoned inside a structure, all infantry gain the follow effects for their weapons.

  1. A much faster rate of fire
  2. Anti aircraft capabilities
  3. Reduced damage per shot

It is highly recommended that you garrison a mixture of infantry in structures to provide a strong defense against infantry, vehicles and aircraft foolish enough to be in range of the structure.

Attacking Occupants / Countering Garrisons

Occupants inside most civilian structures are not immune to shells, bullets, rockets, lasers and the various types of ordnance being propelled at the building. There is a 33% chance that an attacker's weapon will not damage the structure but instead hurt occupants inside the structure instead. The exception is the heavily fortified concrete bunkers, that your infantry might discover on the battlefield.

The most efficient way to counter garrisons, is the use of artillery due to their long range and effectiveness vs structures. Heavy bombers or a mass of vehicles / infantry can overwhelm defenses as well.


Controlling civilian structures, doesn't just slow down enemy forces. Using the idea of map control and supply lines that you find in grand strategy games, garrisoning a structure will provide $10 every 5 seconds.

Although it seems like a small amount, think about those large city maps which have numerous structures to garrison and even on smaller maps, that bunker or lone house which might have been ignored before, is now a potential economy support structure, with a very low entry cost.

Base Expansion

In a major departure from tradition CNC style gameplay, garrisoning a structure, grants a build radius! You can place any normal structures next to a garrison structure and so can your allies as well. If you ever want to build an outpost or base within a city or to rapidly expand your front lines, garrisoning and holding onto civilian structures is vital.

On another note, the outhouse and life guard hut can no longer be garrisoned, because that's just stupid.

Developer Notes

  • The original idea of garrisoning civilian structures for AA combat and base expansion comes from the excellent WIP mod Robot Storm by Apollo at
  • Due to hardcoded limitations in YR, all infantry inside a garrison must have AA capabilities for the logic to work correctly. If you were to place a ground only attack infantry and an anti air only infantry in the same building, they would be unable to fire at any targets.
  • Due to hardcoded limitations in YR, the range of all infantry inside structures is fixed. As such mortar infantry might have more range when not in a garrison. This is balanced out by the improved combat abilities whilst inside a structure (more time to set up weapons, ammo, etc).
  • AGSA is influenced by RTS such as Supreme Commander, Act of War, Civilisation and Hearts of Iron.
