THE SCOUTS | UX / UI ARTIST

THE GAME

A PvP Matchplay game where you shoot a bow and arrow at a target.

You have three attempts taking alternate shots. The player with the highest points is declared the winner.

THE PREMISE OF THE GAME

What can affect the shot?

The players takes turns shooting at a target with a total of three rounds.
They will need to judge the distance and the flight path.
Other factors that will affect the shots are weather and equipment.

All this equipment can be found in the loot boxes.
The player can use the shard to boost equipment stats for a limited time.

The equipments will consist of:

String

Gloves

Arrowhead

Arrow shaft

Arrow feather

Bow

The chest (loot box)

Loot boxes are a way to offer players the chance to win sought-after items at random. Finding these rare items will help the player advance such as upgrading equipment. This will increase the stats of the equipment which will enhance gameplay.

Each chest will have a random rarity attached, these rarities are common, rare, epic and legendary. Each chest will also have a random number of badges which represent equipment. The rarest chests will have a larger number of badges and a bigger chance of getting rare badges.

OPEN

Each chest will have an unlock countdown time before you can open it.
The time increase with how rare the chest is.

COMMON (10 seconds)

RARE (2 hours)

EPIC (4 hours)

Legendary (6 hours)

Each chest will have a random number of badges which represents the types of equipment. Each piece of equipment will have a random percentage chance of rarity.

Inventory screen functionality

Currently, the Inventory screen contains 3 different types of items:

MERGE

The player can merge chests together to create a new chest.
Merging the chest can result in a chance of creating a new chest with a higher rarity, which could mean more equipment with a bigger percentage chance of a higher rarity.

SHARE

The player can choose to give or sell a chest to a friend.
They can also sell on marketplace, for candy (currency) and trade for equipment or shards.

The shard (boost equipment stats)

The shard is an item that can be found in the chest or won in a match-play.

The player can use a shard as an upgrade item. This can be achieved by merging a shard with a piece of equipment.
The stats of the merged equipment will now be boosted for a period of time.

USE

Each shard will have a rarity attached which is common, rare, epic and legendary.

COMMON (30 Minutes)

RARE (3 hours)

EPIC (12 hours)

Legendary (48 hours)

The shard with a higher rarity will boost the equipment over a longer period of time giving that equipment a better stat boost.

MERGE

The player can merge the shard together to create a new shard.
Merging the shard can result in a chance of creating a new shard with a higher rarity.

SHARE

The player can choose to give or sell a shard to a friend.
They can also sell on marketplace, for candy (currency) and trade for equipment or shards.

The candy (meta-currency)

The candy is an item that can be found in the chest or won in a match-play.

The candy can be used to upgrade equipment as currency and can also be used to purchase from the store.
Candy can also be shared among friends and used as currency in trades.

SHARE

The player can choose to give candy to a friend.
They can also use the candy as currency in the marketplace.

User flows and wireframes for player objectives

Inventory screen

Concept 1

The player lands on the inventory screen when they click on the inventory icon from the navigation menu.

There is an empty slot available, which will give the player the indication that there is a new item to unlock. It creates a bit of mystery about what this could be, giving the player the incentive to continue progressing through the game to find out.

If there is more than one item being added in future updates, the design can be scaled to a 4 by 4 grid.

Concept 2

This concept gives the elements larger space which could be more impactful to the player.

Although the elements are bigger in concept 2, the flexibility of concept one is the prefered choice. If more items were added at a later stage concept 2 will need to be redesigned. Whereas concept 1 is more scalable.

The preferred option for scalability

Concept 1

This concept allows seamless scalability going from a single grid system to a 4 by 4 grid.


PROTOTYPE DEVELOPMENT

To understand how the user interacts with the inventory, I focused on the 3 key tasks, which is unlock and open a chest, merge two shards and share candy with a friend. I mapped user flow and user journey for these 3 tasks to identify potential blockers.

The chest gameplay loop

The player wins a match and is rewarded with a chest.
Each chest has an unlock time which increases with the rarity.

 

 Task 1: Unlock and open a chest

USER JOURNEY

Unlock function

When the player clicks the oak chest the related information is seen in a pop-up window. Here the player has insight into the number of badges in the chest and the amount of time to unlock. The player can merge, share or unlock the chest.

Reveal items and equipments

Once the unlock time has elapsed the player can now open the chest. This chest has 6 badges and these badges can be a duplicate of either an item or an equipment. This chest has 3 badges of candy and 3 badges with an arrowhead called the stinger.

The player has collected the correct number of the stinger badge to be able to upgrade this equipment. A notification will appear on the navigation menu to let the player know there is an equipment available for upgrade.

Opening the chest

If the player clicks the chest from the previous screen they will be navigated to the chest inventory screen.

The chest inventory cannot store more than 8 chests at one time. This prevents the player from hoarding items and this will force the player to unlock merge or trade the chests.

The Shard gameplay loop

The player wins a match and is rewarded with a shard.
Each shard a boost time which increases with the rarity.

 

 Task 2: Merge a shard

USER JOURNEY

Shard merge flow

If the player clicks the shard from the inventory landing screen they will be navigated to the shard inventory screen.

The shard inventory cannot store more than 8 shards at one time. This gives the player an added decision layer of when to boost their equipment stats. Given that there is a limited time the stats are boosted this will give the player the incentive to continue with the game.

Merging two shards

When the player clicks the Sapphire shard the related information is seen in a pop-up window.

When the player clicks merge a new pop-up window will appear. From this window, they can swipe up or down to change the shard they wish to merge. Once the two chosen shards have merged a new shard will appear with updated stats.

The candy gameplay loop

The player wins a match and is rewarded with candy.

 

 Task 3: Share candy with a friend

USER JOURNEY

Candy share flow

If the player clicks the Candy from the inventory landing screen they will be navigated to the Candy inventory screen.

In the candy inventory screen, the player can see the total amount of candy they have.

Sharing candy with a friend

The player clicks the share action from the candy inventory screen. The candy share option appears as a pop-up window where the player can set an amount of candy to share with a friend. The player can add which friend to send the candy to.

Research

Learning objectives

Objective 1

Understand the end-to-end journey of how and why participants use items from the inventory.
Understanding how and why participants interact with the items and how this affects their gameplay style.

Objective 2

Uncover participants' thought processes and prior experiences when taking the actions relating to each item in the inventory.
Interested in seeing what their thought process is behind the process, and if/why they have done so in the past. It creates a clear understanding and a good foundation to build from.

Objective 3

Discover if any of the items have made an impact on the participants' gameplay style and how they feel about progressing with the game.
Interested to see if the participants understand the core gameplay loop and how these items affect the way the game is played.

Research objective

Identify areas of friction that the users may face when interacting with the inventory function.

Research method

User interview

For this research study, I am using a one-on-one user interview where I will be conducting moderated usability testing using a prototype. With this method, I will gain a deeper understanding by using follow-up or probing questions to see the exact decision the participants take at each step.

Player archetype

A casual gamer who plays games in their spare time or at social events.

Participants

5-8 participants are recruited depending on how the studio recruits, which could be from surveys, forums or from the game app.

Call duration

1-hour video call over zoom. The call will be remote with screen sharing capabilities and the participants will have a link to the Figma prototype at the start of the call.

Call Plan

Introduction (10 minutes)

In the introduction section of the call, I will go over the agenda of the call with the participants so they know what to expect. At this point, I will share the Figma link for the prototype walkthrough and I will inform the participant that I will prompt when to move through the prototype.

Moderated usability testing (15 Minutes per task)

The task-based walkthrough will consist of three tasks for the participants to complete.

  • Unlock and open a chest, starting from the inventory landing screen.

  • Merge two shards, starting from the inventory landing screen.

  • Share candy with a friend starting from the inventory landing screen.

Task one

Inventory screen

Now that we have gone through three tasks what would be the next action you would take?

Observations

There are a few aspects that are vital to the functionality of the inventory system. Throughout the interview, I will be observing and tailoring my questions to understand the following functionalities.

  1. Does the participant understand the different rarity values?

  2. Is the chest unlock times clear?

  3. How does the participant feel about the implications of merging two items?

  4. What would the participant do with upgrade equipment received from the unlocked chest?

Wrap-up (5 Minutes)

Finally, a call wrap-up where I present a chance for the participants to ask any questions they have. Also, take this opportunity to thank them for their time and ask if they would be interested in being a part of future research.
