Basically OTA

Basically OTA, or BOTA, was originally masterminded and created by Thor. Thor, like many old time OTA players, felt that the spring conversion of OTA was lackluster and sloppy at best, as Spring's lack of features at the time made it difficult to properly recreate the feel and gameplay of OTA. But instead of working to create an exact conversion of OTA, he decided to create his own mod in the flavor of OTA, calling it "Basically OTA". BOTA was first released as Version 1.0 around the same time as AA Version 1.35.

Instead of aiming to change the game's balance through things like armor classes and weapon types as Absolute Annihilation has, BOTA uses the same type universal damage stats as OTA, and instead determines unit balance through basic stats such as Hit Points, Speed, and Range. All of the units in BOTA have recieved a substantial Range and Speed increase. Also, like OTA, Missile Towers can shoot at ground, laser and ballistic weapons can hit and kill air (because of the universal damage system). Mobile Units in BOTA 1.4 also have a much greater speed and acceleration than the previous versions.
