Let’s face it: with the mini-map and overhead view, stealth isn’t a terribly viable playstyle in Dinogen Online. If anyone’s going to be running a Suppressor, it’s because it’s attached to their favorite gun by default. So why not add more?
The OTs-38 could fill a decent niche as a high-powered integrally suppressed pistol, like the Detective Special but trading in a bit of range and capacity in exchange for stealth and slightly higher damage. (I recommend at least 100+ but with a substantial drop-off at range to keep the Desert Eagle and Rhino relevant.) On top of all this, it’s already been in TWP2. Just be sure it fires from the 6 o’clock this time…
The SIX12 could fill a similar niche in the shotgun category. A six-round capacity would keep it from being as spammy as the Origin-12, Jackhammer, or even the humble M1014 and properly relegate it to a hit-and-run ambush playstyle. Once again, we could lift this straight from TWP2 with some modifications.
On the other end of the spectrum, the VSS Vintorez as a DMR. I’d personally balance it more in line with the SG550 or RSASS, keeping high mobility and stealth in exchange for a reduced capacity or less range than either of those weapons. Since DMRs tend to rely on longer ranges and multiple follow-up shots, having an integral suppressor here makes the most sense gameplay-wise.
Finally, the VKS Vychlop for the Sniper Rifles, which are seriously lacking in meaningful differences as is. Not sure how you’d balance it, but at least it would shake things up in a weapon category where every weapon generally feels the same.
