A few mutually exclusive barrier upgrades that:
1. Make a 1x3 barrier wall that can be walked through but still reflect projectiles
2. Make the barrier charge trajectory to be fired towards someone, at the cost of weakening the projectile significantly
3. Make the barrier able to absorb projectiles to charge cells and tools in your secbelt
4. Make the barrier unable to make a reflector field, but removes slowdown
