SEPTEMBER 11, 2026 waves update

WAVES MODE OVERHAUL

Rounds arrive as a steady stream, from every spawn point on the map.

ADDED

• Enemy stream — a round's enemies arrive a few at a time. Each kill makes room for the next.

• Every spawn point — enemies enter from all teams' spawns, out of sight when possible.

• Extra entry points — larger maps with far-apart spawns get more places for enemies to come in.

CHANGED

• Round size — rounds keep growing the deeper you go.

• Enemy counter — counts every enemy left in the round, including ones still on the way.

• Party size — bigger parties face more enemies at once instead of longer rounds.

AUGUST 26, 2026 AI training v10

ADDED

• Accuracy scoring — round-end score from the share of shots landed.

• Reward channels — recorded games tag every reward with the skill it trains.

• Recorded history — games from an older reward set were kept and trained on.
