1. Surrender
- Counts as a victory/defeat
- No/less infra damage
- More loot
- More approval rating drop
- No beige
2. Ceasefire
- All war statuses are removed (Blockade, Ground Control, etc.)
- MAPs do not increase
- Approval rating increases
- Lasts a fixed amount of time (maybe 12 turns?)
- Cannot attack during the ceasefire
- Wars still expire during ceasfires
- Can only be done once a war
3. Colonization
- Counts as a victory/defeat
- Opponent takes 25% of city income
- Lasts for a set amount of time unless ended by the opponent
- Requires the opponent to have soldiers
- Kills a number of soldiers proportional to the total population per turn, and colonization ends if no soldiers remain
- Major approval rating drop
All options are under the pretense that the opponent accepts the offer.
