The best general Retro Tower Defense loadout is one affordable opener, one group-damage tower, one durable-target carry, one support or control tower, one economy option and one flex answer. A practical owned example is Doombringer or Bling Bloxxer to open, Mage for groups, Noli or Chance for sustained damage, Helper Bot or another real support, Tycoon or the current economy option, and a final slot for detection, a second carry or the map objective. Treat those names as substitutions, not mandatory ownership.
Six-slot loadout card
Placement and upgrade order
Place the opener on a bend or repeated path segment. Buy the smallest upgrade that reliably stops early leaks; four weak placements are usually worse than one tower at a meaningful breakpoint. Add group damage when enemy count becomes the issue, and add the carry when one durable target becomes the issue.
Choose the final damage cluster before placing support. A support radius that clips only one tower wastes both cash and board space. Keep economy on safe outer tiles. If you must choose between another farm upgrade and surviving the next wave, defend first.
Adjust by mode
For Normal, keep the opener cheap and use towers you actually own at developed tiers. For Hard, move damage and detection earlier; the farm slot can become a second defender on an unfamiliar route. For Insane, every slot needs a clear contribution and support coverage should be planned. For Endless, reserve end-board tiles and decide which opening tower will later be sold.
Solo teams need role compression. A tower that covers both early waves and detection can free a slot. In co-op, divide responsibilities before queueing: one player opens, one brings economy, and one owns support timing. Do not assume a teammate has detection or boss damage without checking.
Replace the failed job, not the entire team
If you leak before placing the expensive carry, change the opener or first upgrade. If groups pass but the boss dies, improve AoE or coverage. If only the boss survives, preserve wave clear and change carry/support timing. If a property cannot be hit, use the flex slot for detection. If the board is stable but cash arrives too late, measure farm payback rather than adding more farms automatically.
Before you queue
- Read current tower cards; tier, Tower Path and balance changes matter.
- Check the map and difficulty preview for detection or restrictions.
- Confirm the cheapest legal first placement.
- Identify the main cluster, exit backup and economy area.
- Keep emergency cash for an unknown wave.
- Change only one role after a failed test so the result is understandable.
No single named team stays best after every update. The role blueprint remains useful because it tells you exactly what a replacement must accomplish.
Example substitutions by collection stage
A new account can use documented starters or level rewards for opening and coverage, then save the carry slot for its best developed summon. A midgame account should replace the weakest job first: better AoE does not fix a boss loss, and a rare boss unit does not fix an unaffordable opener. An endgame account can compress roles, but it still needs to prove detection, placement cost and map uptime.
Two-run verification
Run the same map twice before declaring the loadout stable. Record starting cash, first placement, first upgrade, when support and economy enter, and the first near-leak. In the second run, change only the slot tied to that failure. If the result moves later, keep the change; if the failure stays identical, restore the original and test timing or placement instead.
For co-op, show loadouts before queueing. Assign one opener, one support owner and one economy plan, then make sure the combined team still has group and durable-target damage. A coordinated accessible team is more reliable than several expensive individual builds with duplicated weaknesses.
