Can I earn money and Gems offline in Merge Tower Defense?
Offline earning is a thing in this game, but the rate at which you earn is currently very low. If you aren't playing actively, the better option would be to earn while AFK. Just stay logged in, and you'll get even more free Gems!
Merge Tower Defense FAQ
The best strategy for this is to place high-HP units (like Dreads) front and center, then surround them with high DPS units, such as Hellfire. This way, the zombies will rush to what are essentially your tanks while getting picked off by the damage dealers.
Taking down a boss will be a matter of sheer firepower in Merge Tower Defense. The best recipe here would be to go with Dreads, Destructors, or, potentially, Ghost Eyes. The latter option is good if you're struggling for in-game money.
Merge Tower Defense is, naturally, a TD game on Roblox. You can merge your defensive units, upgrade your tower, and even purchase new, stronger towers. Still, you're up against a horde of mindless zombies who wouldn't know a genuine fortress if it hit them in the nose, so the attackers won't stop coming!
