Many people know that some rounds of BTD4 and BTD5 are limits to the game, as they are either the last programmed round, or a simple failsafe. The round limits of BTD4 only consist of one: round 250, which sends a rush of 999 B.F.Bs, making it nearly impossible, as they move EXTREMELY fast and will go through the map extremely quickly. Round 400 in Apopalypse in BTD5 is the limit, if you beat it, you just get killed by the system. This next limit is a failsafe and was only in until the Brickwall update, the limit is when you reach round 500, as then it sends a infinite rush of Zomgs until you die, once you die, it stops, it supposedly sends 999 zomgs, but this cant be confirmed, and they are extremely fast, faster than a pink bloon even, and are almost impossible to hit due to them being too fast for most projectiles to register a hit on them.
