The first corporate war began when Euro Business Machines attempted a leveraged buyout of Transworld Airlines (TWA), a failing business. EBM attempted to make a deal with the CEO of TWA, but the CEO of TWA let the deal fall through. Orbital Air, another corporation interested in buying TWA (and desperate to claim TWA's air traffic facilities) blocked EBM's buyout attempt. After realizing what had happened, EBM sought to eliminate Orbital Air's chances of purchasing TWA. EBM hired terrorists to kidnap Orbital Air's business negotiation team, en-route to meet with TWA. However, the terrorists failed in their mission, and later it became known that EBM was responsible for hiring them. Orbital Air, after discovering the identity of their attacker, recruited the Zetatech technology corporation as their ally in the conflict. Zetatech's hackers began a large-scale net attack against EBM, but EBM was able to repel the attack and force Zetatech out of the war.
