I often find myself walking by Core Electronics and scratching my brain... wondering why this building is here. This got my imagination started and I had some ideas. This is what I remember.
1) Mines that can be detonated by remote.
2) A new trap that electrocutes anyone that walks over them, adding a slight freeze and damage.
3) Cellphones that modify the messaging interface and colors.
4) A new electric gun and melee.
5) Playable Electric Guitars.
6) Instant Zone warping Orbs that allow players to warp to any zone on the map. (like using the flute in Zelda: A Link to the Past) these should obviously be consumables, and not cheap either.
(I also assumed it was going to open with a lot of electronics and appliance furniture)
