Odyssey Mode (BTD6)

About Odyssey Mode

“	Odyssey Mode is here! Join Modysseus on an epic adventure each week!	”
	~ Bloons TD 6 - Patch Notes! Version 19.0

Odyssey Mode is a new game mode added in BTD6 on Version 19.0. It is similar to Odyssey Mode in BTD5 Mobile, but now there are limited towers available to place into a "crew" boat. There are three modes, and each of them reward differing amounts of Monkey Money and Trophies. Unlike in BTD5, all three Odyssey Modes can be attempted in one single week, although the Trophy rewards are capped at the highest completed mode.

An internet connection is required to initiate an Odyssey on each island, although the rounds can still be played offline as long as there is an internet connection before pressing the "Play" button.

Description

Summary

Building an Odyssey detailed description

Every week the developers at Ninja Kiwi choose a set of maps for all players. In the beginning, there are three selectable difficulties: Easy, Medium, and Hard. Higher difficulties provide bigger and better rewards. The player must complete all the maps in the chosen difficulty in order with a single set of lives for all the maps to complete the Odyssey challenge. All islands (or in this case, each of the "maps") are the same across all Odyssey difficulties, and all players will receive the exact same island archipelago, but the difficulty sets on each island will be different.

In each difficulty, the maps are in order, with the easiest maps coming first and the hardest maps coming last. There are three maps in Easy Odyssey Mode, four in Medium, and five on Hard. The first map will guaranteed be a relatively easy Beginner Map. Maps in between may be of any Map Difficulty, with harder maps being placed in harder difficulties. The final map will always be Intermediate on Easy, Advanced on Medium, or Advanced or Expert on Hard.

In addition to additional harder maps, harsher restrictions to certain tower types and/or quantities may occur on harder Odysseys. For instance, sometimes Hard Odyssey will ban one extra tower, or it may impose a hard cap on certain tower types (e.g. up to 5 Monkey Subs for Week 2).

Unlike in BTD5, if the player loses a map, the player will simply be required to restart that map from the start unless a Continue is bought (which costs 100-500). The only way for the player to restart the entire Odyssey is via the button at the map selection.

Special Rules

• Lives are carried over each island, and the player may not generate any lives above the given maximum under any circumstances (e.g. from Support Chinook, or Marketplaces with the Healthy Bananas MK). If the player lost some lives on the previous island, they are unable to regenerate lives past the amount of starting lives brought to the current island.
• Freeplay Mode cannot be played, although Freeplay rules may occur if the island's rounds are set past Round 80.
• Powers once used are permanently used up for the entirety of the Odyssey Mode, so use them very wisely.

Version 19.0 Official Patch Notes

The Version 19.0 official patch notes provided by Ninja Kiwi provide a good overview on what may come next for future Odysseys. Due to currently being on the first week of Odyssey Mode, there is little confirmation on what will truly be consistent on all upcoming Odysseys. (If it does change, please update the summary section.)

Description

• Odyssey Mode is here! Join Modysseus on an epic adventure each week!
  • Earn Trophies by completing Easy, Medium, or Hard Odysseys
  • Choose the Hero, Monkeys, and Powers that will allow you to win each map in that Odyssey
  • Uniquely themed Odyssey challenges each week
  • Odyssey badge to show off total Odyssey stars collected (find it in your Main Menu Profile)

Dev Notes

• Odyssey has been a long time coming - we wanted to make it as variable and customizable as possible at launch, with extensible systems that allow it to evolve update to update; thanks, awesomer community, for your requests and patience!
• Trophy rewards do not stack from difficulty to difficulty - the 50 Trophies from Hard difficulty is the maximum, so if you play Easy and win 15, then play Medium which has a 25 Trophy base reward, you will only get the 10 Trophy delta between those two reward levels
• Badge stars also do not stack - the 5 stars from Hard is the maximum per Odyssey; we made both of these design calls so players do not feel compelled to play all 3 Odysseys to maximize rewards or bragging rights - play all 3 only if you’ll have fun doing that!
• Powers can be purchased in-game up to the value that you put into your Crew loadout; for instance, you don’t have to have 5 Supermonkey Storms to allocate 5 to your Crew loadout and doing that gives you the option to buy up to that Crew allocated number if you find that you need them
• A few things that work differently for Odyssey - no freeplay, no replays of completed maps or difficulties, and no co-op; our goal was to keep Odyssey purely focused on challenging, multi-map, single-player adventures - then evolve from there

Crew

Odyssey Crew on Easy

Before starting an Odyssey, the player must equip a crew of different Monkeys (towers) and Powers. One Hero must be joined as well, and will sit on the ship's bow as the "captain". The chosen towers, powers, and hero are the only ones can be used during the Odyssey. Likewise, the only types of Insta-Monkeys available for placement are the tower types recruited to the crew.

Sometimes certain tower types or certain Heroes may be unavailable for the crew. Therefore, it is not possible to equip those tower types or place a certain Hero as the "captain" of the Odyssey.

Difficulty	Lives	Max Monkey Types	Max Monkey Crew Size	Max Power Types	Max Power Crew Size
Easy	200	12*	30*	8*	20*
Medium	100	8*	24*	8*	20*
Hard	50	6*	16*	8*	20*

* Correct as of the Week 4 Odyssey

Journeying

Odyssey island rules, which shows a collection of maps to complete

As the player journeys through each island, or in this case each respective map, the player will need to complete each island in the same way as be done in a standard game. The game difficulty will be set based on each island. Players are limited to their entire crew to successfully complete each island. This does include the limited Powers the player brings in for the Odyssey journey. Once the final round ends, the player must move on to the next one, and therefore is not allowed to go to Freeplay Mode.

Completing Island 1 (Week 1)

Once an island is completed, the player will move to the next map. The entire crew will remain the same quantities and will not be lost. For Powers, they will simply be restocked if they are used within a certain game Lives will carry over to the next map, whether or not lives are gained or lost. Monkey Money is gained equivalent to as though it were a standard game.

After completing an island, press "Continue Odyssey" to continue the journey to the next island. This will continue until all islands are completed.

Rewards

Collecting the final reward

After completing Odyssey Mode on a certain difficulty, it will reward Monkey Money and Trophies. Trophy rewards are rewarded based on the highest difficulty completed, but the other reward is accumulative. Unlike in BTD5, it is still possible to do all other Odyssey Mode variants after doing an Odyssey of a certain difficulty. However, once a certain Odyssey Mode variant is fully completed, it is not possible to do that variant again until the next week's Odyssey.

Each map completed earns the usual Monkey Money and Medal in addition to any Odyssey Rewards.

Difficulty	Monkey Money ()	Trophies ()	Odyssey Stars ()	Others
Easy	50	15*	3	One Road Spike*
Medium	125	25*	4	One 3-2-0 Monkey Buccaneer*
Hard	200	50*	5	One 4-2-0 Tack Shooter*

Tips

• It is best to attempt the Hard Odyssey, as it will yield the most trophies. Do not attempt Easy or Medium Odysseys first unless you have too much difficulty with the Hard Odyssey.
• It is recommended to bring stronger towers in general that requires minimal amounts required. For instance, it is best preferred to bring 5 Subs with Sub Commander synergy than 10 Dart Monkeys with Super Monkey Fan Club.
• Recommended heroes are Benjamin, who can restore lost lives, or heroes that can easily deal with early game such as Quincy and Obyn Greenfoot.
• If you have the Healthy Bananas MK and you lose lives, it is recommended to farm those lives back before ending the map, as any lives you lost after the end of the map cannot be restored on the next game.
• Always bring Cash Drop, Super Monkey Storm, and Monkey Boost as your powers when possible. They are the strongest powers and will be more helpful when compared to other powers. Avoid bringing Road Spikes because they consume one whole slot each and usually do not contribute much towards turning the tides of difficult situations.
• Remember that you are allowed to pause and exit the map when you're about to lose and not lose your progress, so use that if you need to restart a round.

Bugs

Cornfield map (completed, left) on Hard Odyssey Week 4

• There exists a bug in Week 4 where Cornfield's map is represented by a colored void (blue, orange, or dark purple) instead of the expected cornfield segment due to a missing model.

Trivia

• The Greek monkey is apparently named Modysseus.
• The maps to be played are the same for all players.
• The tower types maxes and power types maxes are referred both as "seats", according to the Crew section of the game.
• Unlike standard games, Medium Odyssey and Hard Odyssey both have 50 less lives than in normal Standard Medium or normal Standard Hard.
• So far, the first hard-capped tower cap is Monkey Sub on Week 2, with a hard cap of 5 on Hard Odyssey.
• Impoppable maps do not force you down to 1 life, but Mana Shield is disabled as in a normal Impoppable game.
• Losing on Odyssey Mode does not produce a special game over screen like what the BTD5 Mobile's Odyssey Mode does; instead, it looks and replicates exactly the same as the game over screen in a real game.

Odysseys History

• Week 2's Odyssey "You Have My Bow" is the fist Odyssey to feature Reverse Mode and Impoppable Mode. It is also the first Odyssey to feature ending rounds that are different to their respective mode difficulty.
• Since Week 3's Odyssey "A Walk in the Park", first Odyssey to also reward a free Power or Instamonkey, all future Odysseys also rewarded a free Power or Instamonkey as a third reward on top of the Monkey Money and Trophies rewards.
• Week 3's Odyssey "A Walk in the Park" is the first Odyssey to feature starting rounds that are different to their respective mode difficulty.
  • Week 3's Odyssey "A Walk in the Park" is also the first Odyssey to have modifications during the release of the Odyssey. Originally on the fifth map for Hard Odyssey (Tree Stump Half Cash), the starting cash was $325, which when halved due to the Half Cash game mode, resulted in $162 starting cash. It was corrected to $650 starting cash ($325 after Half Cash applied), as it was originally impossible to complete without Monkey Knowledge.
• Week 4's Odyssey "A Toasty Tail" is the first Odyssey to feature rounds beyond 80, and it is also the first to feature Double HP MOABs and Apopalypse, although Apopalypse was only available on Medium Odyssey for that week.
• Week 4's Odyssey "A Toasty Tail"  is also the first Odyssey to have difficulties with another difficulty's subdifficulty.
