Tower Defense

JS/Canvas/Go/Websockets

Large tower defense map. But it's really a PvP game. All games are order N, number of players. There will be N entrances. Each player will be given a region around an entrance where only they can build. But the rest of the map is a fight for space. The map is a grid, like DTD, but with everyone fighting for space, it will be hard to build a good maze. All mobs have a health and dollar value. All damage done returns some $, but the killing shot gets a bonus.

Towers

• Basic: cheap, decent all around
  • Area
    • Vampire: Same as basic 2 but only extracts $, deals no damange
    • Sniper: Huge area, very high damage, very slow
  • Machine gun: rapid fire
    • Damage
    • Area
• Area: Damages all mobs in a region
  • Higher speed
    • Area
    • Drain: Small hit on every mob in range every frame
  • Higher damage
    • Double shot: can store one hit allowing it to fire two rapid shots before dropping down to it's lower speed
    • Area
• Slow: no damage, but reduce speed.
• Boost: Increases damage of 8 adjacent
  • Curse: Decreases damage and rate of adjacent
    • Silence: Same as curse, plus, disables the most expensive adjacent tower
    • Curse 2: Further decreases damage and rate
  • Boost 2: increases damage further and rate
    • Area: increases area significantly, and damage at Boost 1
    • Boost 3

The ROI for selling decreases at each stage, probably 90%, 80%, 65%.

Controls

You can place a new tower over an old tower, this way you won't lose a space you control.

Towers have different priority settings; first, last, most health, least health. Possibly a control to select a rectangle an limit firing to that boundary.

During the pre-game phase, you can only build in your region.

Mobs

• Basic
• Troll (high health, low $ per hit, high for kill)
• Heal (recovers health, not $)
• Fast
• Armored (high health, no $ until below 50%)
