Creating an Alamo like situation can be fun. Sometimes i will intentionally lose most of a battle until the point where there is an equal number of friendly AI on the field compared to the reinforcement count. This way i am the last alive with one reinforcement ticket left, you can tell this because its the point of a mass spawn by your AI.
The plan is ruined if you die between that point because there will be one AI and yourself with only one reinforcement ticket left, meaning you have to defend the idiot. Either way after that point i defend the CP and kill all remaining enemy AI depending on how well off i allowed them to be. Most maps work well because there are many easily defendable CP's.
