TL;DR
- Fractures and Organ Damage should be rare or impossible to acquire
- The map should be at low level light levels, no 100% darkness. Flashlights and flares are still useful, but you can see in the dark without them.
Edit
- Barricades should have significantly higher chances to block bullets.
HvH as a game mode is unlikely to ever reach a stage of being an independent game mode that does not require staff to run it, but I think there are a few mechanics that could be changed to help enhance the base game mode to be less frustrating for the players.
Fractures and organ damage need to either be made very hard to acquire, or outright impossible outside of minor heart damage from revives. The issue is that it is incredibly easy to suffer fractures and organ damage from sustained gunfire, as gun damage is balanced around you are fighting xenos and not being shot at intentionally.
Being revived in HvH is rare as it stands, but the amount of damage you sustain makes it almost impractical to do so, this leads to players sitting out or waiting for a ERT reinforcement, which then encourages staff to send reinforcements. Thus players lose agency or attachment to their character since characters become less personal and more cannon fodder. If players only had to deal with their damage and internal bleeding, there’s more incentive for people to be revived.
My second point is to remove complete darkness. At minimum the map should be set to a low-light level, enough that you can still see targets but that flashlights, flares and NVGs are still desirable to use as they make target identification quicker.
The issue here is that the HvH meta becomes everyone running around in complete darkness, people who use their lights get killed and everyone else is playing pin the tail on the donkey with a blindfold. These kinds of fights are boring and destroy any attempt at allowing a static frontline to form, as now everyone is just roaming around like a hive-less xeno deathball. This also makes NVG users the king of HvH (Mainly Specs, SGs and the rare NVG CLF spawns), and dying to someone who can see while you can’t see a thing is boring.
HvH is the only game mode where people want to play FTL, since they get access to NVGs.
EDIT
Based on discussions I also believe that increasing barricades to have a much higher chance to block bullets would be a great change.
As it stands, barricades are a noob trap in HvH, they offer no actual cover to the user, and make defensive fortifications very hard or impossible to hold.
If barricades worked more effectivly, it would further help allow actual frontlines to form, alongside the light change.
These three changes I feel would go a long way into making the game mode less frustrating and more enjoyable to the average player.
