Blue Thunder M-45 and Red Thunder M-24 are the protagonist fighters of Thunder Cross series and they also appeared in Air Force Delta Strike.


The "Thunder Cross squadron" get powered by destroying red interceptors revealing a power pod. The first is always a Option, followed by a Speed Up. The next one is a weapons pod, cycling through the main weapons. After that, multiples and weapons alternate until you have four multiples (two if played in co-op mode). Options are situated top and bottom of the protagonists' fighters and options can be manipulated by stretching up and down, giving Thunders a huge convienience of taking out strategically emplaced enemies without flying towards their alignment. The next pod cycles through the super weapons, before turning into a normal weapons pod. The super weapons have limited ammo and are capable of firing through the scenery. Also, each of the main weapons can be powered up by collecting their pickup again.
