Matches

OpenSeason has two types of matches for DeathMatch mode, Ranked and Unranked.

Ranked Matches, XP and multipliers

Ranked Matches

Ranked matches require a minimum of 10 players to start, and they don’t include bots. We're also using a slightly modified version of the Halo 2 system, and ranked matches are the only way for players to earn experience points (XP).

The schedule for ranked matches can be found on the OpenSeason website.

XP Calculations

Once a game is completed, the game awards or removes XP from each player depending on the final result. This is achieved by consulting a table (shown below), dependant on the difference in level. In broad terms, winning or losing matches against similarly-ranked players nets a lower XP gain/loss, whereas winning or losing matches against players with higher skill gaps will gain greater rewards or greater loss. For a given player in the game, the table is consulted to perform a matchup against every other player in the game - if the player has completed a ranked match with 10 players, the table would be consulted to determine the XP gain/loss for 9 players. Once these values are tallied, the total is divided by the amount of enemy players, to gain a final XP value for the game as a whole.

Level difference	Higher win	Higher loss	Lower win	Lower loss
0	100	100	100	100
1	92	108	108	92
2	85	115	115	85
3	79	121	121	79
4	74	126	126	74
5	70	130	130	70
6	66	134	134	66
7	63	137	137	63
8	60	140	140	60
9	58	142	142	58
10	56	144	144	56
11	54	146	146	54
12	53	147	147	53
13	52	148	148	52
14	51	149	149	51
15+	50	150	150	50

Worked example

To give an example of this system in use, consider a Ranked Match in which there are four players;

First place: Player A (Level 10)

Second place: Player B (Level 7)

Third place: Player C (Level 8)

Fourth place: Player D (Level 5)

To calculate Player A's total XP gain, the table must be consulted three times - once for each player they matched up again. In this case, they won against a player with a three level difference, a two level difference and a five level difference. Thus, it can be determined that Player A earned 79, 85 and 70 XP - respectively. This value is then summed to get a total of 234, before divided by three to get an average value of +78XP. This calculation is done for every player to determine each player's XP gain/loss.

1-50 Ranks

With the player's total XP values known, the game can display a single rank number as a representative of their overall skill. Ranks are indicated by a 1-50 value, with a new player holding rank 1 and the highest-ranked players holding rank 50, with most players averaging around rank 10.

Rank level	Minimum XP	Maximum XP
1	1	99
2	100	199
3	200	299
4	300	399
5	400	499
6	500	599
7	600	699
8	700	799
9	800	899
10	900	999
11	1000	1099
12	1100	1199

Rank XP gain modifiers

For the systems mentioned above, another factor to consider is the XP modifiers based on rank. To assist new players in leveling up, those with lower ranks face less severe penalties when losing matches while they are at lower levels. This percentage gradually decreases as they level up, and by rank 29, it no longer applies. However, OpenSeason’s XP operates on a zero-sum system, meaning there is a fixed amount of XP available to the entire player base, and the raw XP gain/loss mechanics ensure that when one player loses, the winning player gains the same amount of XP lost by the loser. To uphold this system, higher-ranked players start experiencing the opposite effect on their wins. Once players reach rank 42, they begin earning a reduced percentage of the XP they would normally receive, with this penalty increasing with each rank, ultimately capping at level 50, where max-rank players earn only 50% of the XP for a win.

Unranked Matches

When a Ranked Match is not taking place all matches default to Unranked Matches. These can be joined at any time and don’t have a minimum player requirement. Players do not earn or lose XP while playing unranked matches. But they do require to be engaged in order to earn beans.

Below are the main differences between Ranked and Unranked matches:

Match	Ranked	Unranked
Min. Players	10	1
Duration	10 min.	10 min.
Bots	No	Yes
Join Anytime	No	Yes
Experience Points	Yes	No
Beans	Yes	Yes

Reward Allocations

$FU Allocation is based on the amount of beans each player earns during a match and the different multipliers applied to those beans. The multipliers are applied at the end of each match.

Epochs and Seasons

An Epoch lasts for one week and during that week, players earn Epoch XP (EXP) which are used for the Epoch’s multipliers. At the end of each Epoch (Sunday, 00:00 UTC), beans are tallied, reset to zero and players receive their respective $FU earnings based on their share of total beans earned during the Epoch.

A Season has 12 Epochs and a Season XP (SXP) which is used to reward users at the end of the Season. SXP is reset at the start of every Season.
