Super Robot Taisen L Cheats

Atross
Destroy Atross with Iczer-3 during stage 26. Atross joins during the intermission after stage 34.

Duel Gundam AS and Buster Gundam
On stage 6, place units on all 6 Meteor Breakers before enemy units destroy them. You will get the two mecha during the intermission after stage 33.

Ken and the Blade Gainer
Fulfill any of these two: 1) Take the Godannar route after stage 6. Destroy Lou with Goh or Anna on stage 10A. 2) Take the Godannar route after stage 19. Do not allow Ken and Lou to get destroyed until the Blade Gainer TDM appears on stage 22A. If you did 1), Ken will join after the stage 19 route split if you did not take the Godannar route. Otherwise, both ways you will get him after stage 22A.

Michel
Take the Macross route after stage 28. On stage 29A, have Michel destroy at least 8 enemy units. Michel will rejoin after the mission. Note: If Michel's kill count is already 999, the kill count will not increase and this secret cannot be obtained. Also, Klan will be able to pilot the VF-25G Messiah after stage 29A if you did not obtain this secret.
