Anniversary Campaigns span long periods of time and often include mini-events within them, like special login bonuses and the Board Game Campaign.

Because these are very special events commemorating the launch of Gundam UC Engage, the rewards players can earn from these campaigns are often very valuable. These include Diamonds, gacha tickets, and even UR Custom Tickets, Unit Enhancement Pts., and Haro Coins.
Completing all of the Anniversary Campaign Achievement Rewards typically rewards players with a Special UR Select Unit Assembly Ticket that lets players pick a unit from a select pool of mobile suits or pilots.
1.5th Anniversary Celebration Campaign

Battle Rush is an event that features a set of battles with increasing difficulty. Here, each mobile suit carries over its HP from the previous battle.

Each Battle Rush iteration typically rewards players with Diamonds, Custom Tickets of all rarities, and a Title. Players should try grinding through the entire event, or at the very least, up until the last stage. By then, a player will have earned all of the Diamonds and the Custom Tickets.

Challenge Battle is an event that features a series of missions where specific MS types, categories, or unit categories gain unique buffs, and units that fall under these tags become far more suitable to use than others.

Each Challenge Battle iteration typically rewards players with Diamonds, UR Custom Tickets, and a Title. Just like with Battle Rush, players should try grinding through the entire event, or at the very least, all the way up until the last stage. By then, a player will have earned all of the Diamonds and the Custom Tickets.

Clan Battles (CB) are seasonal events that pit a player and their clan against others, in a race to inflict as much damage as possible on a designated enemy team within a given time.

Clan Battle gives top-tier rewards like Diamonds, gacha tickets, Custom Tickets of all rarities, Clan Medals, Grand Coins, Haro Coins, Coins, and a Title.
While the Diamond and Custom Ticket rewards are tied to spending AP and BP, players need to put in the effort to score as high as they can, both in the Clan and Individual modes. The higher a player's rank, the more Haro Coins, Grand Coins, and Clan Medals they will earn.

Combat Power Augmentation Operation (CPAO) is an event mode that allows players to participate in special quests that grant either UR Custom Tickets, Unit Enhancement Pts, EXP materials, or Coins, with a player's score determining how much of these resources they will earn.

Unfortunately, CPAO costs 200 AP to play, which is extremely costly, and the returns are not impressive. This huge AP cost messes with a player's Haro Farm routine, and because of that, it is only recommended when a player absolutely need some of the featured rewards.
Combat Power Augmentation Operation Event

Encirclement Breakthrough Battle (EBB) is an event where players try to fend off an unlimited number of enemies for 120 seconds. For each enemy mobile suit you destroy, another will take its place.

EBB rewards players with Diamonds, Custom Tickets of all rarities, and free fragments for a featured set of units. Sometimes these fragments are for farmable UR units, and progressing enough to get all the winnable fragments should greatly accelerate their Haro Farm progress.
EBB also rewards players with special Event Medals, which can be used on the event's gacha box to win goodies like more Diamonds, gacha tickets, and more.
Encirclement Breakthrough Battles Event

Mission Battle is very similar to EBB in the sense that they're both game modes where enemies endlessly respawn, and the goal is to survive for a given time.

In Mission Battle, players can earn valuable rewards such as Diamonds, Custom Tickets of all rarities, Haro Coins, and a Title. As with the rest of these events, players should make as much progress as possible while the event is still active.
Players can get rewards for clearing stages, even if they don't get any stars from the more difficult stages. That said, players should aim to clear all stages, including the final Extra stage and the final stage of the event.
Luckily, it's easy to cheese with extremely durable self-sustaining units like the Titania, Penelope, or even the FATB.
Completing all 3 stars should be done on all stages, too, barring the final Extra stage. This is because the final reward for completing the last Extra stage will be a title.

Raid Battle is a cooperative PvE event where players face off against a boss in a game mode very similar to Cooperative Battles.
| Raid Battle Best Rewards | |||

Raid Battle rewards players with modules, exclusive Raid modules that can only be acquired in this game mode, Diamonds, R and SR Custom Tickets, and Event Medals, which can be exchanged for goodies like UR Custom Tickets, more Raid Modules, and Recycle Pts.
Depending on the specific iteration of the event, certain modules featured as rewards in Raid Battle are must-haves. Players are recommended to check out the rewarded modules every time a Raid Battle is active, and then spend all their BP on that specific event if the module makes one of their MSs stronger.

Special Operation is an event mode where each mobile suit used costs points, and the goal is to spend the least amount of points to complete the event's set of battles. Like with Total War, players cannot reuse the mobile suits and pilots they already used to clear the previous battle.

In Special Operation, players can earn valuable rewards such as Diamonds, Custom Tickets of all rarities, Haro Coins, and a Title. The fewer points used to complete the event, the more rewards a player will earn.

Story Events are events that tell the story of Peche Montagne, as well as the other featured stories of the UC timeline, and are some of the best events in the game, as they reward players with brand new units players can later grind for as new sources of Haro Coins.
Performing well in these events gives players multiple free Potential Unleashed levels as well, greatly hastening the Haro Coin Farm process.

Story Events also reward players with Diamonds, Gacha Tickets for the featured Event Banner, UR Custom Tickets, EXP leveling materials, a Title, and Event Medals, which again, can be exchanged for other goodies. While all events are worth grinding, this is especially the case for Story Events, given the quality and quantity of awards.
Completing all of the UR will get the featured units to Potential Lv. 3, which means players will only need 250 more fragments to get them to max Potential Lv. once they become featured Fragment Quest units. This gives them access to a new set of fully leveled sub-skills, and more importantly, a brand new Haro Farm.

Total War features 25 mobile suit icons arranged in a 5x5 grid. Each of these units corresponds to enemy MS teams of varying levels of difficulty.
Like in other modes, each MS the player uses to clear a previous challenge will be unavailable for the remainder of the challenge unless they reset the board. The goal is to clear as many of these teams as possible, with bonus rewards being granted for each line of five enemy units cleared.

Total War rewards players with Diamonds, lower-rarity units, UR weapon chips, and Total War Medals, which can be used in the Total War shop to buy exclusive blueprints/pieces of units of different rarities.
Out of all the events, Total War is one of the grindiest, considering how there are 25 battles to go through, and players cannot reuse mobile suits they have already won a battle with.
However, the mode is still well worth grinding, especially since the Diamond rewards are tied to clearing battles and not the bingo lines. Even if players know for certain that they will not win all the battles, they should still at least clear all the battles they know their mobile suits are capable of winning to earn at least some of the rewards.

World Raid is an event game mode where players deal a collective amount of damage to the World Boss on successful attempts, with the goal of destroying the World Boss after a given damage threshold. Do take note that it has been a very long time since the last World Raid, and it is one of the rarer events in the game.

Unit Enhancement Chips
|
World Raid rewards players with gacha tickets, a UR Selector Ticket, Diamonds, UR Unit Enhancement Chips, and UR Custom Tickets.
It is very likely that players will get all of, if not most of, the rewards from the Total Damage Rewards and the Destruction Reward, given that the top active players of the world will all contribute greatly to this cause.
However, players will still want to spend their extra AP on this event whenever active, and try to deal as much damage as they can with each attempt. This contributes to a player's individual damage count, and the higher the individual damage count is, the more Diamonds and UR Custom Tickets they will earn.

Once a month, Gundam U.C. Engage holds Engage Day, which gives players the chance to get 10 free pulls from the Engage Day MS and Pilot gacha banners.
| Engage Day Banners | |
|---|---|
| Number of Free Pulls: 10 | Number of Free Pulls: 10 |
Though the units may not be strong in the game's current meta, they can still give beginner players additional copies of mobile suits they can use for their Haro Coin farms.

Gundam U.C. Engage's newest event mode which tasks players with completing a series of missions in the shortest amount of time possible. The less time spent clearing these missions, the more rewards they will get.

Support Gear (R, SR, and UR) |
Players be warned, however, as even veteran UCE players have a tough time completing all the missions. It is still recommended to try these missions, however, as they can still give Diamonds, Custom Tickets, and even Gears for Support units.

Every event is almost always 100% worth grinding as far as a player's account and current roster can take them. This is simply because all events (except CPAO) reward players with Diamonds, and all of them offer other very valuable resources too, like Rainbow Haro Coins, UR Custom Tickets, gacha tickets, or even mobile suits and pilots.
Events are also released every week and often span two weeks. Most people who are very serious about this game clock in every day to put in the effort to grow their account, and this involves grinding through events. Two weeks is often enough time to do everything a player needs to do in the event over multiple gaming sessions, even if they miss a couple of days.
