No Oddjob crouching! Paintball mode and Proximity mines. Thinking back at that single centered joystick + D-pad makes me wonder how we ever played it to begin with.
Putting proximity mines on the ammo crates and then immediately picking up the crates so they respawned and the mine was invisible was just... chef's kiss
IIRC mines wouldn't be triggered if it was yours and you interacted with them in some way. But because the way Goldeneye handled objects like the ammo crate, anything that was considered "a part of it", such as the mine, disappeared so a new one could spawn. The overall game code knew the mine was still there so if another player grabbed the ammo crate, thus interacted with the mine, it would detonate and kill the other player.
This inspired me to fire up the N64 and try it. First attempt, I blew up the mine accidentally and lost all my health, so you can definitely trigger your own mines. Second attempt, I placed it and picked up the crate, and the mine disappeared! And it could definitely blow up in that state too. But when I tried it again and let the crate respawn, I could see the mine again. So, shrug?
But I'm impressed, I never knew about this till now.
We just didn't know any different! Compared to the precision of FPS games that we're used to now, it would probably feel like painful slow-motion to watch our old Goldeneye matches...
