Early Gondola: Strategy depends upon the location of the Jackal spawns. In order from fastest to slowest:
- Sword-fly to middle platform, sword-cancel over enemy onto departing gondola. The enemy must be standing still.
- Sword-fly to far platform, jump to gondola, stand on railing and trigger enemies, run+jump onto departing gondola.
- If you don't see any Jackals, run all the way to the little ledge, grenade jump onto central platform, sword-cancel to gondola. (risky)
- If you didn't carry over a sword from Delta Halo, reset :^)
Checkpoint Manipulation: By killing all the enemies (especially the turret Grunts) on the outside of Regret's chamber, you should be able to get a checkpoint directly before the fight; 2 Elites from a back room will spawn afterwards, it'd be best to kill them before engaging Regret, as you can revisit this room during the fight for an often consistent checkpoint.
