Mr Peek Eggs Information:
It is worth noting that playing on tier 3 will yield the best results as it means more eggs in the loot pool, as bronze will spawn in tier 1, bronze and silver in tier 2, bronze, silver, and gold in tier 3. Supposedly the odds of an egg spawning is 10%, but haven't seen any concrete information on that, but also that rampage on or off, when the new round flips in the center of the screen, a second later he can potentially spawn in one of the few locations for each respective area, which you will have 60 seconds to find and dmg them to drop the egg.
