UD-8 Kayser in the mission "Endgame"
During "Endgame," the 25th mission (19th if you don't count the training missions), Volition programmers accidentally left 99 UD-8 Kaysers available in the pre-launch weapon selection screen even though the weapon isn't technically introduced until much later in the game. Use them! While they cause a significant drain in your power reserves when compared to other weapons, the Kaysers are the best primary weapons in the game and will utterly destroy the waves of NTF fighters you come across during this mission.
