From a dream I had.
Basically, it was a multiplayer game with the players split into two teams. It was in 3D, but with simple-ish graphics (no textures). Every player's character is highly customizable, and special abilities require "Energy" to function. The energy is acquired by building... I don't remember the name, but it looked like a little tower with a lightning bolt on top. I'll call them generators. They automatically charged up players near them. Players could fight with customizable weapons and special abilities. There were also research buildings that could be used to unlock improved generators, turrets, etc. There was also resource mining. If you die, you go into spectator mode for the rest of the match, and the battles were to the last team standing. So, here's what I can remember of the plot of the dream (to give a hint of what the gameplay would be like):
The match started. I was what looked like a hybrid of a cat and a fighter jet that required energy to fly. I was on the red team. I was quickly building generators and telling some of my Steam friends to guard our base (It was a Steam game, presumably). Then I charged up, took off, and started shooting up the enemy with lasers. It was an exceedingly quick attack. A few passes later, I accidentally crashed into a mountain, creating an impressive crater (there's also destructible terrain!), but survived with all of my energy drained and 10% of health left. I walked back to the base and someone with a medic ability healed me up. Some of the other people went to the enemy base on foot. But the enemy researched a robot factory that produced AI-controlled robots that assaulted our base. We have researched turrets by that time. I took off and strafed the robots with... I think bombs? I had bombs. The rest were destroyed by the turrets, but not before destroying a few of our generators and killing some noob who decided to melee the whole swarm. We received the notification that the enemy has researched nukes, and launched a mass assault before they nuked us, leaving some of our guys to research nukes. A missile fell onto the mountain 4 of my teammates were on, and killed them, in the process blowing up half of the mountain. I flew to their base and found out that they only had one uranium deposit, and it was completely drained. We had 5. I was shot down by someone with a long-range sniping ability (didn't notice that I flew too close to the mushroom cloud and got damaged). I signaled it to the chat before getting killed. There was lots of fighting, trenches were dug, until eventually there were only two people left from each team. They were attempting to snipe each other from a long distance, and 2 minutes later, the red sniper managed to kill the blue one with 1% HP left. The dream ended.
