The Left 4 Dead franchise is based on a series of cooperative first-person shooter, survival horror video games developed by Valve Corporation. Set in the days after a pandemic outbreak of a viral strain transforming the majority of the population into zombie-like feral creatures, the games follow the adventures of four survivors attempting to reach safe houses and military rescue while fending off the attacking hordes.
The games encourage cooperative play between up to four players, each taking the role of one of the survivor characters and the computer controlling any unassigned characters. Players use a combination of melee weapons, firearms, and thrown objects to fend off attacks from the bulk of the infected creatures, while using an assortment of healing items to keep their group alive. Certain unique infected creatures pose a more difficult challenge, typically requiring teamwork to take down effectively. The games are overseen by an "AI Director", designed to give the players a more dramatic experience based on their performance, penalizing players for stalling while rewarding players with special weapons by taking longer or riskier paths. The Director also makes gameplay dynamic, meaning that no two playthroughs are quite the same.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
