This is a really good spacecombat game.
You get a briefing for the battle, then depending on your rank you might get to choose your ship and loadout and later your squads ships and loadout.
Then the BATTLE starts. This game has really really good battles. You can only fly smaller fighters and bombers, but the battles has cruisers, destroyers, titans...you will see huge bams going off, you will see flak defence fire. And you are in the middle, part of a bigger battle. But you can influence it in a lot of ways.
Run interceptors and catch enemy torpedoes so your capital ships win. Or fly air superiority fighters and get those enemy bomers. Or fly a bomber and disable enemy capital ship components.
Or make your squad bombers and protect them with your fighter....
But its not all allout battle, you can have scoutmission in a nebula where you can see anything. Or you get invited to a blackop mission behind enemy lines. Or you are stationed near a civilian structure and have to make sure nothing goes wrong!
But you know what the best part is?This game went open source, there is a fanproject that you use that updates the graphics quite a lot.
And there are countless of total mods with new storyline and everything.
btw, this game is perfectly fine with mouse and keyboard, at least the open source project version is.
