During the initial days of the Fortnite alien invasion, UFOs were only scouting out the island with their flying saucer and gathering information. However, as the abductors began to appear, a lot of NPCs were abducted and replaced with trespassers in order to not draw any suspicion.It would seem that Farmer Steel was among those kidnapped, and once Hayseed found out, he began sending players on various quests to help him prepare for the inevitable alien invasion which was to come. Given that he's willing to fight to defend the island, Dr. Slone now wants to recruit him to the join the cause.Finally, the questline concludes with Hayseed collecting food and supplies to prepare for an eventual attack on the aliens, which is likely why we will soon see Slone in close contact with him in week 6, for she needs as many allies as possible with how sketchy IO is. pic.twitter.com/TPrX5NR9BB— PokeSkull | SUMMER MIDAS (@poke_skull) June 30, 2021In order to persuade him to join the fight, Dr. Slone is tasking players with delivering "Prepper Supplies" to Hayseed's farm.
