I developed a group of modlets to use on my server. I have decided to make them available to everyone. These modletss work on servers with no client side installation necessary, or on single player games. They are all compatible with each other.
Brian's Mod Admin Steel - allows admins to use invincible steel blocks for public horde bases. The blocks do take damage, but the downgrade path ensures that it never actually disappears. When one is destroyed, it is replaced by a copy of itself. As a bonus to players, it also provides a steel upgrade path for iron bars.
Brian's Mod Economy Boost - provides vending machines that act as fully stocked traders that players can place in their bases. These can be purchased from a trader or crafted at a workbench.
Brian's Mod High Level Perks - The maximum character level is increased from 300 to 500. All attributes have been increased from 10 to 13 levels, and most perks have been given 1 to 3 new levels with fun and powerful new bonuses. Run faster, hit harder, be stealthier, and learn new recipes.
Brian's Mod No Stone Age - Eliminates most Tier 0 weapons and tools from loot, while giving a small chance to find low quality Tier 1 items at early gamestages.
Brian's Mod Quality Control - decreases the effect of RNG and increases the effect of quality levels in determining stats for weapons, tools, and armor. Ensures that higher quality levels always generate better items. Also makes the number of mod slots equal to the quality level.
Brian's Mod Stack More - greatly increases stack sizes of most items.
Brian's Mod Stamina Balance - minor tweaks to the amounts of stamina that various weapons and tools use, to offer better balance.
Brian's Mod Zombie Harvest - all zombies can be harvested for the same items you would get from a zombie dog. Get going on those farm plots and hobo stews!
The next modlet is not being run on my server, but makes for a fun short term game:
Brian's Mod Max Level Challenge - This mod starts the player with 3 books - one that that teaches all recipes, one that gives all magazine/book perks, and another that raises the player to the max character level and automatically purchases all attributes and perks. Once you have raised your level through the third book, you will be dehydrated and starving. Finding food and drink is the first priority. Next, the real challenge is to gather everything you need and build a base that can withstand a high gamestage bloodmoon horde by night 7.
