Just play along, please?
Isaac's Plasma Cutter: This gun looks so badass!! I love the design of it and how you can shoot it vertically or horizontally.
Resident Evil Samurai Edge or Matilda: I think both of these weapons are iconic in their respective series but i think i would have to lean more to the Samurai Edge because of how cool it looks and its power is very impressive
Doom's Plasma Rifle: There's a lot of different iterations and designs of this gun but i would probably say that the Doom I/II and eternal is the most iconic design of this gun
007's Golden Gun: This gun has a very peculiar and interesting design, so it would be cool seeing it
What other guns would you think it would be cool seeing in zombies mode?
