If you need a solid competitive TD, check out Legion TD 2.

If you've played the WC3 mod Legion TD, or the SC2 mod Squadron TD, this is basically the same. It's actually made by Lisk & Jules, the original creators of Legion TD in WC3, and a bunch of other maps/mods from the old Blizzard games.

Damn. Their video show of some old bangers. I own so many of them. Maybe time for a revisit for some of them. Just need more time. A lot of it.
