OverwatchTD (PVE Tower Defense)
This is a true, full-fledged tower defense mode made in the workshop.
Mostly everything in the mode is inspired by BTD6, including the 3 upgrade paths and 5 upgrade tiers system.
You can play with up to 3 players total, and money gained is split between the 3 players.
There are 30 rounds, and 3 main bosses which appear every 10 rounds.
Every regular overwatch map is included as a playable track, and there are even a couple of bonus tracks for fun.
