Let me explain myself, in some audio log in OpFor, a scientist said that the creature/weapon can only hook to organic surfaces, which is true. The Barnacle weapon was a really cool weapon in OpFor, but i found it kinda lacking context to be used, it only used as a grapple in some situations and also it's semi-melee weapon that a lot of people not use at all for a a lot of reasons, but what if you add physics to it ? What if you make it HL2 Barnacle ? Just like Black Mesa for HL, this remake is supposed to be reimagining rather than a straight faithful remake, which is good, and also necessary, porting an old HL game to Source means a lot of things have to change, the inclusion of physics alone makes the game completely different as you can witness in Black Mesa, so all in all, it's open to new ideas, and i have one that is, i think interesting, just thing about it, The Barnacle weapon !!
So, as you know, there's a remake in the works for Opposing Force called Operation Black Mesa by a team named Tripmine Studios, which are also in charge of Guard Duty the Blue Shift remake, the team seems to be focused and doesn't lack talent, as you can see in their artworks and the awesome job they did with the weapons modelling and animations.
