Activision is investigating issues revolving around mods and hackers in Call of Duty: Black Ops on PS4 and PS5.

Last week, Activision dropped ports of Black Ops 1 and 2 on PS4 and PS5. Although they don’t feature any significant improvements or upgrades, fans were extremely happy to see these games accessible on PlayStation. However, the fun was spoiled pretty quickly.

Earlier this week, modders and exploiters began compromising lobbies in the Black Ops 1 port, leading to some players calling the game “unplayable.” These lobbies allow you to rank up rapidly and basically make the entire progression system irrelevant. Activision took action pretty quickly and removed certain playlists to address the matter; however, concerns remain.

The Best Call of Duty CampaignsFollowing its debut in 2003, Call of Duty quickly ascended to become the best-selling first-person shooter series ever, a title it continues to hold to this day. That’s almost entirely down to its ever-popular multiplayer, which keeps fans playing day in, day out. But there are, of course, two sides to Call of Duty. Standing side-by-side the PvP are the single-player campaigns, which, for those of us a little unwilling to huck ourselves into the online hellhole and compete in the Call of Duty combat cauldron, tell cinematic stories straight from the front line. <br><br> But which Call of Duty games have the greatest campaigns? IGN’s keenest and most experienced Call of Duty fans have combined to carve out a list of our favourite single-player stories, plucked from all throughout the series’ two-decade-and-change history. We’re looking for campaigns that champion Call of Duty’s greatest strengths: those with great mission variety, ambitious set-pieces, and novel mechanics, as well as the more traditional “great FPS” staples like strong level design and memorable storytelling. Only the campaigns that have it all can truly rise to the top of this list, which means this year’s somewhat muddled Black Ops 7 didn’t quite make the cut. But which ones did? <br><br> Here are our top 10 Call of Duty campaigns.

YouTuber Tdawgsmitty interviewed one of the game’s modders to try and figure out what’s happening. As it turns out, the issue is partially rooted in the fact that the game has exploits left over from the PS3 version.

“Essentially, what you’re doing is that it’s like PS3 where you copy [a save file] to your USB, and there’s a website that lets you unencrypt it,” said the modder. “The site lets you use a jailbroken PS4/PS5, and it will decrypt it for you. The save data is the exact same as PS3. What sucks about this port is that Iron Galaxy and Activision didn’t bother changing the encryption on the files, which is the whole reason why this is available right now. That’s the only reason why.”

The modder went on to note that there are people selling services that allow others to have their stats and game modded. Thankfully, there are no aimbots right now that allow people to easily kill other players with minimal effort. Things could definitely be worse, but it’s unfortunate that the game is so easily manipulated.

I highly recommend watching the whole video to learn more about the situation. Activision confirmed to Tdawgsmitty that it is actively investigating these issues and looking to resolve things. Only time will tell how long that takes, but at least Activision isn’t abandoning these ports after bringing in a boatload of cash.
