Total Annihilation: The Core Contingency [cheats] Hint: Almost every scenario requires you to build up heavy air defenses immediately and then prepare to repel a heavy enemy thrust as soon as your radar towers go up. Build up long-range siege guns ad nauseam and pound the computer player. Hint: Beware the Krogoth!! Unless your defenses are very deep, you will be forced to use your Commander's Disintigrator and the resulting explosion will leave your Commander teetering on the brink. Hint: On maps with rivers, ditch some metal makers underwater where they will remain pretty much safe against the myopic computer player.
