If a tank goes too long without making progress (collecting points or killing), then it will be ginbegin to rust. Rust will slowly damage the tank and kill it. Rust can be eliminated by making progress.
A tank's vision range will be determined by the light level. If an object is located in a high-light area, then it can be seen from farther away. An object in a low-light area can only be seen by nearby observers. A tank will be able to seeksee things which are closer than the light level in that object's location. The bot will be able to see other tanks, as well as other features (bullets in-flight, heat-seekers, maybe mines). The information available about other tanks will be that tank's weapons (maybe).
- Guns of various ranges and, strengths, and reload rates
- Lasers
- Mines (proximity and timed)
- Area-effect (damages nearby bots)
- Heat-seekers (costly and very accurate, but short range and low damage)
- Shields (not a weapon, but a form of protection that comes in different strengths)
