Red Alert 3

At the start of this 3v3 Magmageddon match we see standard infantry from all players except for blue (NeveCheese) who decides to start a bear parade and just masses bears right out of the gate paralyzing the enemy peacekeepers.

After the infantry stage of the match, which never finished for the blue soviets player (NeverCheese) who continually massed infantry, we got to see airfields out of the allied and war factories out of the soviet players. The right side of conflict mainly decided to go on the offensive route just building vindicators and thus forcing the left side into constructing apollos and bullfrogs in order to defend.

We also saw a turret push from green (H2O||OLD) in response to which he got counter-pushed with stingrays and ended up losing his positions, having to retreat, and then quit leaving his resources for his teammates.

Meanwhile, at the top of the map, the blue player (NeverCheese) tries to pull off some sort of infantry swarming tactic which in the end is dismantled by the purple allied player |m8s|Stryderr using his riptides.

The end game ensues as all the remaining allied players get tier 3 and we are met with a fierce battle in the middle just under the big lava mountain where building blocking, desolaters, and a lot of athena shields are used but the right side only manages to push the left side back a little bit destroying one of their refineries in the process.
Some back and forth carries the game a nudge further but the right side having amassed a ton of tier 3 units eventually overwhelms the smaller armies of the left side.
