No.136XCOM 201The core loop
Action → feedback → next choice- 01Set overwatch
- 02Cover a key lane
- 03Enemy movement triggers
- 04Reaction shot resolves
↻Feedback changes the situation — the next round starts from there.
Walk through one round
A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.
- T1
Turn 1 · The situation
The enemy is behind cover at 30% hit chance, but must cross a corridor next.
- T2
Turn 2 · The player chooses
The player sets two soldiers on overwatch over the corridor.
- T3
Turn 3 · The feedback
The enemy rushes in, triggers two reaction shots, and one hit stops the charge.
- T4
Turn 4 · The next decision
Next turn enemies throw grenades to flush positions, so the player must re-arrange the watch.
How it plays
A unit forgoes attacking to watch; enemy movement in its view or designated zone triggers an automatic shot. Reaction shots often carry an accuracy penalty but can stop rushes and protect fragile allies. Enemies learn to route around watch zones, turning lanes into contested space.
What the player weighs
- Guaranteed shot now vs. a possibly better one later
- Wide but thin coverage vs. a focused lane
02Start small
Scope is an editorial estimate for the minimum prototype, not the reference game or a production schedule.
03One mechanic, different implementations
XCOM 2
Overwatch fires on enemies moving in sight with an aim penalty; during concealment, full-squad ambushes trigger together as enemies step in.
Gears Tactics
Players draw the direction and width of an overwatch cone, clearly visualized; enemies moving through it draw fire until ammo or the reaction ends.
The difference worth noticing
XCOM 2 covers the whole sightline; Gears Tactics makes you draw a specific cone, demanding finer spatial planning.

04What could you combine?
Pair overwatch with procedural terrain: read the generated map for likely chokepoints, then place your few watchers there.
