Event NP or Event Neuron Points are a type of virtual in-game currency in Eternal Return.
Description[]
Event NP functions exactly like 
NP and can be used to unlock characters and to purchase most of cosmetics.
The main difference is that Event NP has an expiration time, and will dissapear if not used by then. When purchasing anything, the game will priotize spending Event NP first before using any NP. Each pack of Event NP has it own separate expiration date, which can be be seen by clicking on the Event NP icon at the top right of the main lobby screen.
As the name implies, Event NP is primarily earned as reward from events, though it can also be obtained by:
- Redeeming promotional coupons
- As twitch drops
- Through giveaways
- Daily and special log in rewards
- Clearing Achievements
