What does it do?


Serious Sam Fusion 2017 enables a lot of cool new features, like a common workshop and cross-game mods. All of the games can be started from one application, so you can jump between playing The First Encounter level to a Serious Sam 3 level and back without exiting the game. When listing game servers, servers playing TFE, TSE, SS3 – will all appear in the same list and you can vote map across games if you want. Oh, and owners of our VR games are able to play multiplayer together with their "flat" counterparts!
Since there are so many changes and exciting new features, we'll just go ahead a list them here as bullet points.

لعبة مجنونة وجنونها مو طبيعي Serious Sam Fusion حريقة وأكشن ما يرحم! الجنان واللذة فيها إن الأعداء يطلعوا لك من تحت الأرض ومن العدم، هجوم كاسح وجيوش ينطوا عليك من كل دخشة ودشيشة! وطبعاً هالضغط والتصويب الخرافي ما ينلعب صح إلا بالماوس والكيبورد، تحكم أسرع وتنتيف على أصوله! لعبة تفرغ فيها كل طاقتك وضحك وحماس من البداية للنهاية. تقييمها 10 من 10 وتستاهل كل دقيقة!
