Demo: The Most Realistic Medical, Hit Reaction, & Gore Mod Combo Possible in Arma III [UPDATED 2025]

This demo showcases the best mod combination available in 2025 to introduce realistic medical/first aid, hit reaction, injury effect, and gore effects into Arma III. This combination is specifically designed to optimize game performance as much as possible while still offering believable injury effect and gore enhancements to the game.

Advanced Combat Environment (ACE) + Advanced Combat Medicine (ACM)

Most Arma players are familiar with ACE, and ACE Medical is arguably the most realistic health/medical/first aid system ever implemented in a video game. Advanced Combat Medicine (ACM) expands upon ACE Medical by adding airway, breathing, and circulation management (including chest seals) to ACE Medical, as well as an improved selection of medical items. One very important, yet often overlooked, aspect of realism in ACM is that upon receiving first aid, injured units are not fully “revived” to stand back up and keep fighting, but instead will continue lying on the ground until CASEVAC to a field hospital for full healing. In fact, ACM is one of only two mods in Arma history (besides SLX) that offers this mechanic.

Advanced Wound Reaction (AWR)

AWR is the “bread and butter” of realistic injury reactions in Arma III. Whereas default ACE Medical only includes limping and unconsciousness, AWR adds physical debilitation states in which an injured unit is forced to crawl upon damage to the legs and cannot use weapons upon damage to the arms. The mod can be configured to function based upon damage, pain, or both, and it works for both A.I. and players. Of note: A.I. units will continue to follow their waypoints upon being “incapacitated” by AWR, but simply placing a scripted trigger for each unit in the scenario can easily resolve this issue (If: lifeState _thisUnit == “INCAPACITATED”; then on activation: [_thisUnit] join grpNull; [deleteWaypoint _x] forEachReversed waypoints group _thisUnit;).

Death & Hit Reactions (DHR)

The purpose of DHR is not to make Arma III more “Hollywood,” but to offset the horrible, immersion-breaking “jolt” that units make in the vanilla game upon being hit. If Arma III could be like Arma II and previous titles in which units did not play an animation at all upon being hit, that would be great (because…physics). However, it is much preferable to have units exhibit an exaggerated “pain” reaction upon being hit, vs. flinching unrealistically and providing no feedback to the player that shot them (and turning around to one-shot the player). I personally turn off all the exaggerated, “Hollywood” death animations from the mod and use it exclusively for the hit reactions.

Project Injury Reaction – Ragdoll Physics Only

Project Injury Reaction (PIR) is a great mod, but it includes its own health system and is not compatible with ACE Medical. Fortunately, PIR’s superior ragdoll effects have been preserved for ACE Medical by several mod-makers on the Steam workshop, and this is my favorite one.

Bloodlust

Bloodlust is a mod that often gets eyerolls because it has a reputation for adding exaggerated and unnecessary gore to an otherwise serious mil-sim game. However, IMO this is a mischaracterization of the mod’s purpose. When the effects are properly toned down (i.e. the mod is used exclusively for blood smudging and slow droplet bleeding), the overall effects are far superior to the cartoonish and exaggerated bleeding that comes with default ACE Medical. I personally turn off all Bloodlust effects except for bleeding and smearing, leaving the bleed rate to nothing faster than ~1 drop per half second to preserve frame rate.

Blastcore Murr Edition

Blastcore Murr Edition is not directly related to hit reactions or gore in Arma III, but it deserves mentioning here because it improves upon blood particle effects in the game. Whereas vanilla Arma III blood clouds can look very “video-gamey” (for lack of a better term), Blastcore causes blood clouds to become more “misty” or “steamy,” which is closer to what a hunter sees when shooting an animal with a full-power rifle. Additionally, the mod seems to have an overall positive effect on game performance with relatively modern particle animation effects vs. what was possible in 2013 when Arma III was first released.

Goko Ballistic Impact

I have a love-hate relationship with Goko Ballistic Impact. I like the “meat chunks” and helmet debris that it throws in the air with headshots, but I also think the blood cloud it adds is exaggerated (and offsets the improvement in blood clouds accomplished with Blastcore). However, a unit’s helmet will simply disappear to be replaced with one of the Dismemberment & Gore mod’s damaged head textures without Goko Ballistic Impact, which looks worse to me than having the particles along with the blood cloud.

Dismemberment & Gore

Dismemberment & Gore adds horrific “burst head” textures to Arma III, as well as dismemberment effects upon explosion and falling deaths. While some players might disagree with me, I believe that adding some level of “horror” to a war game is appropriate, whereas it can break my immersion when units die from massive explosions but remain perfectly intact. Dismemberment can be performance-intensive, so the mod also offers a “vaporization” effect as an alternative (which does not trigger with grenades, enhancing realism).

WBK Simple Blood

Last, but not least, WBK Simple Blood offers superior blood splattering effects to those found in Bloodlust. WBK Simple Blood splatters onto more textures than Bloodlust can, and the effects look more realistic while simultaneously being much, much easier on game performance. Unlike Bloodlust, WBK Simple Blood splatters only occur upon a unit’s death. However, I think that’s okay, because anything powerful enough to cause a massive blood splatter would probably be powerful enough to instantly kill a person anyway.
