Lure is an in-game item that can be bought from a Shop or can be found in a Crate. Most Items modify the Stats of the player, and some of them provide additional effects.
Lure
The added loot aliens will be affected by your +% Enemies stat, so there can be more or less than 2 added depending on your character and items.
