Quad has 4 entrances and exits, and all of them are active every round. The Bloons travel through 2 quadrants of the whole map's path before exiting. Each path overlaps with approximately half of 2 other paths, and all exits are at the same spot as an entrance, making it often difficult to see when Bloons are leaking. There are 4 trusses that block line of sight, make all Bloons (including blimps) immune to all attacks while under them, and are removable for $1500 each. There is a pond in the middle that allows water-based strategies on this map.

Recommended towers and upgrades
Sauda — Due to how Quad's lanes overlap, Sauda's Sword Charge ability can damage all Bloons twice. Her main attack can also deal with half of the map and covers that half relatively effectively, especially coupled with stuns such as Relentless Glue, leaving only the other half to be concerned about. The fast leveling on expert maps further increase Sauda's power on this map due to the high boosts provided by Sauda's higher levels. With Giant Condor, Sauda becomes even stronger on this map, as many more Bloons can be moved into the lane that Sauda deals the most damage to.
Glaive Lord — After the version 43.0 buff, Glaive Lord has become very strong on Quad. The path layout of Quad allows Glaive Lord's rangs to repeatedly bounce all over the map, dealing massive amounts of damage.
Spiked Balls and Spiked Mines — One reason Quad is one of the hardest maps in the game is how its lanes overlap, making it easy to suddenly lose to Bloons leaking without being noticed. Spiked Balls and Spiked Mines solve this problem by tanking leaking Bloons from two lanes for each, largely turning Quad into a two-lane map instead and giving extra peace of mind for Black borders, where leaking Bloons can now be easily identified as those who breach the spikes.
Giant Condor — Condor's ability to move many blimps into the same lane effectively halves the amount of lanes on Quad that one has to worry about on most rounds, greatly benefiting strategies involving limited-range towers/heroes like Sauda and overdrives. Condor is also very useful as a regular support tower, stalling rounds very well and moving blimps near the exit back to the start.
