Redline protocol [v0.3]

Follow Us!

Overview:
Redline Protocol is a side-view squad-defense shooter set in a cyberpunk future. Recruit a squad of characters through an in-game gacha (no real-money purchases), gear them up, and hold line while waves of enemies push in from the right. Each of the five classes: Tank, Bruiser, Sniper, Artillery, and Support, brings her own auto-attack style and a tap-to-trigger special ability, so building and positioning a five-woman squad matters as much as raw stats.
Outside of combat, gifts and affection unlock character gallery events narrative scenes and CG art gated behind how well you know each character.
