Nexus Blitz (Project SLIME) was an experimental mode that ran from July 31st to September 11th, 2018. It started being playable for alpha testing on live servers on patch V8.16.
Games on Nexus Blitz generally last 15 minutes and the last event at 18 minutes makes games usually end within the following minutes.
Before entering champion select, you can either choose to go Lane or Jungle.
If you pick Lane you can freely choose your summoner spells, but you cannot pick Smite.
If you pick Jungle, Smite will automatically be picked for you.
Each player selects one champion to ban.
A unique map with a single lane splitting into 2 in the middle, and the top of the map is a jungle with jungle camps and buffs.
Two junglers can work together in each team to secure jungle camps. Jungle experience and gold is tuned to compensate. Also an invincible turret is in the enemy jungle.
Events for both teams such as King of the Hill, Push the Cart and Prize Fight.
A champion taking down multiple enemy champions without dying will become On Fire!, gaining a lot of stats, but also becoming more vulnerable to damage. Killing an On Fire! champion grants a large gold bounty.
Games can be surrendered after the 8 minute mark.
Recall's casting time is reduced to 4.5 seconds from 8.
Starting at level one, while in the fountain gains Homeguard.
The respawn timer reaches its maximum duration at 18 minutes.
Summoner's Rift and Twisted Treeline jungle items are unavailable in this game mode and instead only jungle item is available, Pridestalker's Blade, which can be upgraded with an enchant. Upgrading to an enchant () grants Chilling Smite along with the normal bonuses.
The Monster Hunter gold penalty is removed in this game mode.
Jungle camps taken with more than one champion grant 150% experience and gold split between the champions taking it (compared to 100% experience and gold if taken alone).
Murk Wolf camps consist of one greater and four normal wolves. The former will explode once killed creating splash damage for the nearby wolves.
Crimson Raptor camps consist of one Crimson Raptor and seven smaller ones.
Two camps of Gromp can be found on both sides of the arena in opposite sides of the lane.
Red Brambleback and Blue Sentinel are located centrally and are much stronger. Taking a buff camp gives a supercharged version of the buff to the last hitter and the closest champion who is not the last hitter. They both spawn at 1:45. They grant 200 locally and 60 globally to all champions on the slayer's team.
Crest of Insight grants its usual effects but additionally increases the CDR cap to 50% for the duration of the buff.
Click the giant cannon next to your fountain to launch yourself across the map! At your base, launch your champion anywhere on the map after a small delay. On impact deals some damage, applies ability effects, and pushes away nearby enemies.
The whole team can pile into this vehicle, with the first player to click acting as driver. Take a leisurely cruise around the map until you hit something and the sled explodes, damaging and knocking up nearby enemies. All aboard for a wild sled ride from your base to almost anywhere on the map. If you've entered the Battle Sled while someone else is driving it, you can press [B] to exit the Battle Sled.
The theme song of URF Deathmatch is a repeated segment of Welcome to Planet URF.
If the player equip the Poro on Fire icon, the champion will be followed by a Poro on fire while playing the game mode. It is similar to the two poro following each champion in Legend of the Poro King.
Minions with the blessing of Blitzcrank buff will pop up the Does not compute emote before the grab.
Loot Teemo event will feature a slightly bigger than normal Happy Elf Teemo as the event monster.
The Teemo has a dropping present VFX, similar to a Move Quick VFX. However, the real skin does not have this.
Nexus Blitz return to live servers from December 6th, 2018 to January 21, 2019 (11:59 p.m. PT).
Map art has been updated to be prettier and more polished using SR assets.

Map has been adjusted to increase jungle variance, reduce snowball, and enforce a longer laning phase.

Red buff has been moved down towards top lane.
Blue buff has been moved into the middle jungle to encourage fights around bot lane.
Jungle experience and gold has been decreased over game time to account for the 4th camp.
Jungle camp damage/health/resist scaling has been reduced. This should make it easier to jungle alone as the game progresses. Jungling together is still important early and still gives bonus gold/XP for the entire game.
Gromp no longer takes bonus damage from single target spells or when CC'd
Wolves still explode because it is the biologically correct thing for wolves to do.
Minions now spawn slightly more often.
Minions are worth slightly less gold and experience.
