Diffusible toxins produced by Prey impact interactions of Attackers, Defenders and Prey!
This can make battles interestingly unstable and change the outcome depending on the toxin production rate. Like this simulation with a winner found only after 380k steps:
Battle Royale with Prey toxins
battle_royale_v10_tox001_extra_long_1000p.mp4At low prey toxin production rate, the Defenders (orange) and Prey (blue) win against Attackers (red)! Firing of T6SS shown as green triangles.
battle_royale_v10_tox0001_1000p.mp4At 10x higher rate, the simulation is undecided for a long time.
battle_royale_v10_tox001_1000p.mp4At 8x higher from there, the Defenders would ultimately win (if this would run even longer).
battle_royale_v10_tox008_1000p.mp4A bit higher diffusible prey toxin production (shown as green toxin fields) results in Attackers winning (no Defenders left).
battle_royale_v10_tox0085_1000p.mp4After another slight increase in the toxin production rate, you get a long battle between Attackers and Prey.
battle_royale_v10_tox009_1000p.mp4If Prey produces enough diffusible toxin, they kill everyone. They pay a high price for synthesis and lysis-dependent release of their toxin.
