- Engineer: a support trooper that automatically builds turrets, mines, and barricades
- Stealth: vanishes while standing still, then dashes in and knifes enemies from behind for an instant kill
- New enemy — Stealer: a fast, tiny raider that races to battlefield items and steals them for the red army
- New enemy — Breacher: a lumbering bruiser that smashes through your built barricades
- New enemy — Teleporter: opens portals that blink a pack of enemies forward, right over your walls
- New enemy — Jetpack: a flyer that soars over cover and barricades and lands on top of the map
- Shimmering cloak effect for the Stealth unit
- Massive battles stay watchable: under crushing unit counts the fight eases into smooth slow-motion instead of stuttering
- Reworked health bars and unit visuals
- Big fights use less memory by freeing up GPU resources from off-screen enemies
- Round-start lag spike when large armies all picked their paths at the same instant
