From my experience playing the Infection mode in Minecraft, having a strong base defense is crucial to surviving waves of infected players and mobs. One of the best strategies I found was to equip automatic weapons like the Scar-L Tactical and AK-12, as they offer a good balance between fire rate and damage. These weapons make it easier to hold choke points and fend off large groups rapidly approaching your base. Additionally, unlocking Sculk identities such as the Sculk Witch and Vindicator added a unique layer of gameplay, allowing for more specialized defense tactics. Crafting corroded or reinforced materials to build your base provided stronger resistance against both player attacks and infected mobs. I also noticed that using TNT strategically to create traps can slow down infected waves, giving your team more response time. It's important to coordinate with teammates on voting for roles and managing reload times efficiently to maintain a continuous defense. Overall, combining weapon proficiency, crafting knowledge, and team coordination significantly enhances your survival chances in the Infection mode on Minecraft.
