Roadworks is the 3rd level of the Giant Tree's campaign and is a fairly easy level as it gives many resources and tower bases throughout and is very easy to create multiple mazes with powerful towers.
It's important you get weapons to deal with the small enemies as you are going to need to focus your towers on the big ones even if you have a weapon such as the Shotgun.
Waves
As you can see on the right, each wave complete gives 200 resources and 7 tower bases, a very high amount for this level.
This level has a mix of heavy lumes and fast small ones.
One of the few levels that has two bosses.
Directions is determined by the in-game map of the level.
Wave 1
Rhino will spawn shortly after the Walker Warrior.
The Walker Patriarch will destroy and bases you have made and attempt to go down the second left line straight towards the core. Because of this, focusing on it is a very good idea and building in preparation for this route.
You can find more tips about the Walker Patriarch on it's own page.
Setting up one tower at the top west spawn is a good idea so they take damage before approaching the south side. If this tower is a Focus, it can do over a million damage in the level.
It's important to stay alive because towers cannot reach enemies shooting at the core in this level.
There are many bosses in this level and it is important you build towers that can damage them.
Closing off the shortest routes to the core (the two middle ones and the left side) is the best way to make the longest possible route for lumes and give you the most time to deal with them or wait for later spawns to arrive at your towers.
