Last Updated: September 20, 2026 | One of the biggest shops this site has covered, straight from Roblox’s own sales data.
Build a Military Base is a free strategy game. You build up a base, unlock tanks, helicopters, jets and mechs, then fight bosses or other players with them. It launched in November 2025 and has already passed 15.6 million visits. Updates land every two weeks, and each one tends to bring a fresh code.
The shop here is enormous. Over 200 items are for sale, and two of the ladders inside it are worth understanding before you spend anything.

Cash is the main currency, and it is sold in packs that get cheaper per unit at the bigger size.

0.0049 Robux each |
| 50,000 Cash |

0.00249 Robux each |
| 500,000 Cash |

A separate “Pile of Cash” line sits in the shop too. It is priced differently from the packs above. The two are not the same ladder, so check which one you are buying.
Mythic Shards are tied to the game’s boss-fighting loop and sold in three sizes.
| Pack |
Price |
| 50 Mythic Shards |
699 Robux |
| 100 Mythic Shards |
1,399 Robux |
| 250 Mythic Shards |
2,999 Robux |
On top of all that, the shop sells over 150 buildings. It also sells a paid Auto Reroll feature and numbered “Patch Bundle” items tied to specific past updates. One older perk, “2x Coop Drop Chances,” is no longer for sale. A newer one with a similar name replaced it.
Tips for New Build a Military Base Players
- Redeem the working codes before you build anything There are 25 active codes right now. Most hand over a crate, and a few give a real building for free.
- Buy the biggest Cash pack you can afford The 500,000 Cash pack costs 0.0016 Robux per Cash, far cheaper per unit than the smallest 10,000 pack at 0.0049 each.
- Watch for the two different cash systems in the shop Regular Cash packs and Pile of Cash items are not the same ladder. Check which one you are buying before you spend.
- Save Mythic Shards for boss fights The game’s own description ties fighting bosses to earning rewards, and Mythic Shards are the ladder built around that loop.
- Check whether a listed perk is still for sale before planning around it Some older items in this shop, like 2x Coop Drop Chances, are no longer for sale. A newer version with a different name usually replaces them.
- Do not expect a real badge ladder yet Only one badge is tracked here, a legacy Tester badge held by a small number of players. There is no real ladder to chase.
