>Start RA2:YR skirmish as Yuri.
>Combine natural barriers with gatling turrets, gatling tanks, and walls, so the enemy can only attack your initial base on land from specific bottlenecks.
>Set up psychic towers around bottlenecks.
>Run any stolen tanks into your grinder so you can build more psychic towers. Any time you're not doing this, you're making more gatling tanks or slave miners.
>Psychic towers increase build area.
>Create ever-encroaching wall of psychic towers and base defenses. Continually move more forces to the front of the blob. Place miners at each ore field you encounter.
>Rush tech and oil buildings with engineers for bonus land grabs and extra cash to fund more towers. Bonus vehicles go in the grinder. Paratroopers go in the grinder.
>Use the tower build area to drop new barracks and war factories near the front of the blob as needed for more rapid unit arrival and production.
>Create transports and extra MCVs to rapidly move build area and psychic towers anywhere preemptively for surprise attacks or to restrict enemy movement.
>Each deployed MCV is an improvement to build time. Better build time means more towers.
>Continue to expand any new blobs of tower land until they link together.
>Once enemy gets artillery and can take your towers out from afar, build magnetrons to pull their artillery into your wall. If a tower doesn't get them, the gatling tanks will.
>By the time you've reached the other side of the map, you should have enough gatling tanks and magnetrons to start the attack on their base.
>Set up war factories and barracks outside of their entrances, pump out magnetrons, gatling tanks, and engineers.
>Punch hole in defenses with magnetrons. Mop up units with gatling tanks. Rush buildings with engies.
>Set up psychic towers outside of any buildings you capture. Place UFO over the first power plant you can.
>Continue to spread into their territory until you've absorbed their base rather than destroyed it, and the entire map is covered in your color.
I love using this strategy. It's more like playing Agar.io than a C&C game. It'd be interesting to see what'd happen if both players tried to use it against each other at the same time.
