Our independent guide examines the core systems of Chaos Gate (Classic)—campaign flow, random missions, squad building, mission editing, and vehicle use—so you can develop strategies grounded in the game's documented features without relying on undocumented shortcuts.

01 / THE GUIDE

Assess Campaign Entry Points

Play the first campaign scenario both after a set of random missions and directly from the start. Record squad strength, mission difficulty, and narrative pacing to see which entry aligns with your preferred challenge level.

  • Try a few random missions first to see how squad experience affects early campaign difficulty.
  • Keep track of which scenario you are on to avoid missing linked narrative events.

02 / THE GUIDE

Random Mission Reward Log

Complete several random missions and note the experience and power awarded each time. Use this log to anticipate which mission types provide the most useful upgrades for your current squad composition.

  • Use random missions to trial unit combinations before committing to the campaign.
  • Note the rewards from each mission to plan future squad upgrades.

03 / THE GUIDE

Unit Role Matrix

Create a table listing each Marine type you own, their primary weapons, and ideal battlefield roles. This visual aid clarifies how to combine Terminators, Assault Troopers, and Devastators for balanced tactics.

  • Mix unit types to balance firepower, durability, and mobility.
  • Review each Marine’s weapon options to ensure coverage against both infantry and heavy targets.

04 / THE GUIDE

Vehicle‑Infantry Synergy Test

Run a scenario where a Predator tank supports a Devastator Squad, then repeat with a Rhino APC supporting Assault Troopers. Observe differences in firepower and mobility to inform future deployment choices.

  • Test custom missions in both supported resolutions to verify visual clarity.
  • Save frequently while building complex layouts to avoid loss from unexpected crashes.

05 / THE GUIDE

Custom Scenario Playtest

Design a short custom mission using the editor, then play it at both supported resolutions. Evaluate whether HUD elements stay clear and whether unit AI behaves as expected, adjusting the design accordingly.

  • Pair heavy vehicles with Devastator Squads to maximize area‑effect damage.
  • Use transport vehicles to reposition vulnerable units safely across the battlefield.
