After some discussion in the Alien Swarm: Reactive Drop Discord, the new plan for sentries is as follows:
- Sentries with ammo remaining no longer explode when destroyed.
- Sentries with ammo remaining are deconstructed when their health reaches 0 rather than being destroyed.
- If a sentry is awaiting assembly and not currently being assembled by any marine, damage dealt to the sentry adds to a special progress counter. If this counter exceeds the assembly progress, the sentry is instantly disassembled and placed on the floor.
- Alien damage is currently set to disassemble a sentry that is as close to being fully built as mathematically possible after it deals about half the sentry’s health. For a sentry that was half assembled and then abandoned, it will be disassembled after 75 damage. If a sentry is placed and then immediately abandoned, any amount of alien damage will disassemble it.
- All of these parameters are adjustable via convars, for challenges or for testing.
