In the OakyMod, a nation's population limit can exceed 600 units at the end-game, and many new Unique Units and other changes shine during the much larger battles that result: The OakyMod features a slightly-tweaked implementation of Draxsath's Population and Technology mod, as well as units recovered from the campaign from probed's TaP Redux mod. Some buildings, such as the Redoubt and Wonders, also receive health bonuses to compensate for massive siege army components

Additional changes are planned, including more defensive technologies and more upgrades for defenses.

Barbed Wire, which when combined with effective wall placement allows for effective area denial during the Industrial Age.

Flak Mortars and Flak Artillery, which add a powerful, high-health, unique splash defense starting in the Industrial Age to counter large swarms of weak infantry.

Tiered Walls, upgrading from palisade walls in the Ancient Age to stone, crenellated castle walls, and force fields.

One critical but certainly optional addition is the creation of a defensive play style - expanding your defenses beyond ineffective watchtowers and weak forts - through the following additions: The OakyMod adds a number of changes to the game that are designed to extend match durations and provide multiple, compatible gameplay styles.
