new crossovers should be similar to the Viper Commander war bond let me explain
the Viper Commando warbond is heavily inspired by the Predator films yet it is still recognizable as something in the helldiver's universe. It also came with the jungle planet type. all they would need to have is a automaton enemy that can turn invisible with a strong melee attack and a strong hitting but slow to fire ranged attack and they would have the perfect predator crossover updates
let's say they did a crossover event with trench Crusade having things like a trench map type with a enemy that resembles a unit from trench Crusade (like a flying range Terminids that has a fly look resemble the herald of Beelzebub or ranged type of voteless/illuminate cultist that take inspiration from heretic Troopers) but still looks like something helldivers. if you don't care much for the crossover or don't know what trench Crusade is it won't affect you but if you are fan of French Crusade then you depreciate the reference
