Intro I think, all regular Zombie Escape players have heard a lot of myths about what weapon is the most effective against so called "bosses". I've heard them too. Some people say M249 is the best in this case. Others say that P90 and TMP are better. So I decided to make my own research about what weapon is the most effective. I hope this will help PlagueFest ZE server fail less at bosses. Criteria The most effective weapon will be the one that has the highest number of damage (damage, NOT bullets, will be explained later) per second. Reloading time will be included. I was testing all weapons on two maps: my ze_Portal_Story_v3_1 and Luffaren's ze_predator_ultimate_v3 as they show in numbers what damage each weapon deals to boss. Most maps have the same health system, so the results will fit on any map. Numbers and calculations When I was testing Portal's new HP-bar system, I noticed that some weapons deal more dmg/bullet than others. For example, M249 deals ~2dmg/bullet while MP5 - just 1dmg/bullet. I don't know why exactly does this happen. So, I've tested ALL weapons on both Portal and predator maps. Here are average numbers: As you can see, more powerful weapons have more damage per bullet. Now lets watch at actual fire rate of each weapon. By fire rate I mean the time you need to fire a FULL clip and FULLY reload. After getting these numbers we can calculate the actual fire rate: BULLETS/SEC = CLIP / TIME. Now, when we have DMG/BULLET and BULLETS/SEC numbers, we can calculate DMG/SEC. DMG/SEC = DMG/BULLET x BULLETS/SEC. That's what we were looking for. We have next results: According to this table, we can select the winner: 1st place, gold medal, M249 with 14.79 dmg/sec 2nd place, silver medal, P90 with 14.04 dmg/sec 3rd place, bronze medal, Galil with 11.71 dmg/sec Epilogue I hope this information is going to be useful. Thank you for attention.
