Phobocore is a two-player hotseat game, where the aim is to capture all the planets onscreen by shooting them. It’s sort of a cross between Asteroids and Risk/Galcon, with a respectful nod to open field overhead shooters like Robotron, Bezerk or Gauntlet.

Boys vs. girls. ┃: GAMEPLAY :┃ Phobocore is a a simultaneous two player game. The goal is to capture as many planets as possible. * You capture planets by shooting them - eventually they will turn to your colour. * If you shoot a planet enough, it becomes locked to your colour - these planets cannot be re-captured by the enemy. * The more planets you capture, the faster your ammo refills (orange bar). The more locked planets you hold, the more powerful your bullets become. * You can fly through neural (white) or enemy planets. You cannot fly through your own planets. * Shooting the enemy freezes them momentarily, however they also absorb your bullets for their own ammo store. * Powerups occasionally appear - these give you more ammo, and can provide the vital edge you need to capture more planets than your opponent. * The red bar goes up the more planets you lock. Once you have locked 30 % of the planets on screen, you win. ┃: CONTROLS :┃ Player 1 (pink, left ammo bar): W,A,S,D and space Player 2 (blue, right ammo bar): Arrow keys and right-CTRL ┃: OPTIONS :┃ Commandline options: -f run the game in full screen mode ┃: TIPS :┃ Early on, every bullet counts. Fire accurately and efficiently. It may seem frustrating at first, since you can't shoot very fast. Early in the game, aim to quickly but efficiently capture as many planets as possible, and pick up powerups if you can. Don't waste ammo locking too many planets early in the game - it's more about quantity not quality at this stage. As you capture more planets, your fire rate will go up. Once you have a reasonable fire rate established, start focusing on locking planets too. This will increase your bullet power, meaning you can also capture/lock planets faster. Take opportunities to steal any weak planets owned by your opponent (the smaller ones) with a quick circular spray of bullets - this will seriously impact on your opponents fire rate, frustrating their efforts to capture/steal/lock more planets. Try not to fence yourself in. Keep in mind that planets you capture become blockades for you, but become open space for your opponent. Rather than spraying a whole 360 degree circle of bullets to capture all the planets in your vicinity, try doing 270 degree sweeps, leaving yourself a exit small hole of neutral or enemy planets.
