Level 0.3 is the third tutorial level of Infinitode 2. It introduces the experience system, tower selling, and platform bonuses.
Overview[]
The 11-tile road resembles a corner piece but with the corner inside the shape. There are 2 platforms in the middle of the level far enough that a 
Basic can not reach enemies (hence why it is disabled for the level). There is also a 30% Scalar source next to the lower platform and a 40% source next to the Portal (but obviously since miners have not been introduced yet, they are just for cosmetic). An equaliser will play to either side of the music player.
It is possible to achieve the «How?» achievement on this level. After selling the 
Sniper, just build the next one on one of the non-bonus platforms, causing the base to explode due to the reason «Quest failed». You can also sell the second Sniper once you buy it, although the failure message will not make much sense, as there was no longer a quest to fail.
Dialogue[]
Brackets indicate an event that occurs between the dialogue. Italicised content represents the corresponding quest.
ADVINAS: This next level is not very convenient - Platforms are too far from the road and Basic towers will not be able to reach enemies.
ADVINAS: Sniper tower is well suited for destroying enemies at long range. Build a Sniper tower on the Platform.
[Build Sniper tower]
ADVINAS: Sniper tower deals a lot of damage, but it has low rotation and attack speed.
ADVINAS: When changing a target, the Sniper needs some time to aim, so frequent changing of targets can make this tower extremely inefficient.
[Defeat the first Wave (or just wait until no more enemies are on-screen)]
ADVINAS: Towers gain Experience for killing Enemies and dealing damage.
[Tower experience & level (will vary based on how wave 1 was dealt with or if you are in the Sniper's menu): Towers gain experience for killing enemies. Tower level affects its unique characteristics (unique characteristics have golden color in the tower menu).]
ADVINAS: Some Platforms can give bonuses to Towers placed on top of them.
ADVINAS: Check out this new Platform with Experience bonus.
[Bonus experience V platform appears; Turn on Detailed mode to see all details, Select the Platform with Bonus]
ADVINAS: This Platform will greatly increase the amount of gained Experience, it's a good idea to use it as soon as possible.
ADVINAS: There's not enough Coins for new Tower, but you can Sell the existing Sniper tower to get back some of the Coins spent on it.
[Sell existing Sniper tower, Build Sniper on the tile with bonus (only the tile with the bonus, any other tile causes a Game Over!), Defeat the second Wave (if Auto mode was activated for Wave 1, it will be turned off and you have to manually start the wave)]
[Once the Wave 2 enemies were defeated]
ADVINAS: Towers gain new abilities that significantly increase their effectiveness at the 4th, 7th and 10th levels.
ADVINAS: Your Sniper tower has reached 4-th level and now you can select its first ability. (note: this text does not change even if it isn't true)
[Sniper's menu will be opened, Tower abilities (the first 3 are highlighted in blue if Sniper is LV4): Abilities greatly increase effectiveness of towers. You can select new ability on 4-th and 7-th level of tower. Special ability opens automatically at 10-th level; Select Sniper's first ability; Game speed button: Switches game speed between ×1, ×2, and ×4. Hold the button for a few seconds to pause the game (or put in super slow motion, depending on Settings); Switch Game speed, Defeat remaining waves]

Trivia[]
- This level, like all tutorial levels, will not consume Rarity tickets.
- It is also unaffected by Endless mode.
- 4th was misspelled as «4-th» in the last message, as well as all the ordinal numbers in the Abilities popup.
- Like level 0.1, you do not have to finish all the quests to win the level (Set Game speed is not required).
- This is one of four levels to have only one enemy type spawn from the portal(s), the others being 0.1, 0.2, and 6.3, and is the last tutorial level to do so.
- This is only level where a wave spawns exactly 1 non-boss enemy.
- Interestingly, when viewing the waves, Regulars appear to spawn indefinitely, rather than disappearing after wave 5 (or a multiple of 5) as shown in later levels.
