Eternal Silence is a modification of the source again, along with other mods. Now, stereotype has it, belive it or not, people don't except anything from mods in the terms of entertainment value. And I kind of belived in the same until I have tried this piece, which is a really demanding but unfortunately abandoned game.
Basically, the mod sets you out in the outer space and there are multitiple gamemodes, the conventional includes dogfighting with other ships, assaultinh corvets and then landing on the enemy capship. Once you done that, if you are team is able, you can win the game by capturing all the sectors in the enemy ship.
There is also a CTF gamemode whose elements I can no longer recall, all I know it was fun.
So, now you might ask, what keeps me from playing the game if I had enjoyed it that much? The game's dead, there are only two servers to connect to, both of them is empty, all what's there is void.
Both the playerbase and the developers abandoned the game, the last update for the game was relased in 2010. Summarizing my thoughts, this was a great mod while it lasted, I'd gladly play a round or two in it if it was still active :s
