TLDNR: I Bloody love Stardust Vanguards very much.
Let me start off by saying I really love Stardust Vanguards a lot. Stardust Vanguards is a great Local multiplayer game, but unfortunately no online multiplayer. It has some of the most fun 4 player craziness. The deathmatch is a lot of fun. Especially when you unlock the custom deathmatch. I had a friend over and we played deathmatch with infinite bullets, full reinforcement points, and the maximum amount of pirate encounters. There was so much happening on screen that it was hard to keep track of it all. It was still a ton of fun, me and my friend were just laughing and having a great time. Then we moved onto conquest mode. The mode was alright though nothing too special. It was your average king of the hill style game mode. Now that is out of the way let us move onto what I feel is the main event. SPAAAAAAACE BALL, yeah that is right Space Ball. In my opinion this was the most fun and fast gamemode. Me and my friend started it up and were greeted with a map with lots of walls, a ball in the middle, and a base on each side. We at first thought we were supposed to kick the ball into the other teams base, but it turns out that was not the idea of the game. It turned out were were supposed the get the ball back to our base using our swords, boost, and bodies to move the ball around. The ball almost never went where we wanted it to. It would rather just ricochet all over every wall, only sometimes hitting into our base. Sometimes we accidentally got it in the other persons goal. We played about 6 rounds of Space Ball before trying out the Co-Op part of the game. The Co-Op was your standered survive for as many waves as possible without losing all your lives.
