So how does that game compare with say, the ROs, or more specifically the Darkest Hour mod for RO1?
There's still a couple of glitches that are p. annoying, but overall it's a solid mod. Most of the maps are fun and pretty large, it's infantry only without vehicles and teamplay is pretty important if you want to capture objectives. Has a pretty solid playerbase, too.
It's quite similar to the RO games in gameplay, but with an even greater realism focus. One shot is usually a kill, esp. with K98 or G43. When you survive a shot, you are wounded and might: lose your weapon when hit in the arm, become slowed when hit in the leg (depending on damage, you can be very significantly slowed), get increased weapon sway when hit in the arm.
It's pretty much completely interface-free apart from the faction/class choosing screens, the map and your ammo belt (if you want to see how many clips you have left, you have to press B to take a look at your belt). When you sprint a lot, after a while your char starts to pant and slow down cause of low stamina. Low stamina also increases weapon sway. When you're under fire and especially when comrades around you fall or you get wounded, you get suppression/low morale effects that make the screen blurred and also increase weapon sway.
Weapon selection is more limited and there are less players on the maps (usually the maps are 16v16), but I like how it's focused on infantry maneuvers and the weapons are p. cool. K98k is the standard weapon and it's powerful and accurate, if you know how to use it it's a fucking murder machine (and nothing's more awesome than getting a bayonet kill in close combat). There are 4 NCO slots, two of them Gruppenführer who have MP40 and two of them Truppführer which have G43. Depending on the map, there are also some specialist classes: MG gunner (MG42), heavy grenadier (with FG42) and sniper (K98k scoped). Allies have Garand, Thompson, BAR and some other shit, not entirely sure cause I never play them lol (and garand has horribly shitty ironsights).
Since it's a free Sourcemod, you can just download and try it.

EDIT:
Oh yeah it also has the BEST in-game voice chat ever. When you say something over the voice chat, everyone in your vicinity hears it. Not your entire team, but only those close to you. And also the enemies close to you. It's awesome to hear some Allies talk tactics around the corner and throw a nade there, and it's even more awesome to yell a battlecry and charge at them.
