Level 3

Level 3 is the third level in Infinitode. It costs 3000 Green Papers to open and requires at least 150 Max waves total completed from previous levels combined to unlock.

Design
It is a 35 road map, with one split off about halfway through the map. The level has an 80% difficulty Portal, making it have a 1% difference in difficulty between this and Level 2. There are 16 tile bonuses, with a big focus on Damage (especially Chain Lightning Damage)

Strategy
Put a tower on that Damage 3 bonus on the top right. This tower will do huge damage, so keep it at a high level and well upgraded. For the best results, put either a Missile or Sniper on that tile. This level is the start of a trend seen in later levels, where a cluster of Chain Lightning Damage bonuses are seen on a piece of the map. There is a Accuracy 1 bonus at the end of the track for Splash towers, but it's placement on the map makes it a poor choice for such a tower. The Rotation Speed bonuses can help for Cannons or Snipers if need be.
