A small HUD is displayed under the Mission HUD, showing the total enemies in the wave, the number of enemies killed, the number of enemies escaped, the number of enemies incoming (haven’t approach yet) and the number of enemies left (on screen but haven’t killed). This might be a complement for HUD Progress Meter (showing number instead of percentage). It can be somewhat like this:
The HUD Enemy Counter above shows stats of a wave having 100 chickens in total, all of them appeared (0 incoming), 75 killed, 5 escaped and 20 remaining on the screen.
I suggest the cost of 684 keys. What do you think?
The current one is useful in a wave having very few enemies (like bosses, though they already have progress meter without purchase) and also very intuitive. The HUD Enemy Counter can’t show how many damages are dealed to the enemies, or in other words, it counts enemy as a whole instead of fractions. Therefore, I think these 2 HUDs are both still practical and can complement each other.
Speaking of useless HUDs, I think the HUD Point Indicator is the most ridiculous one. The total score is already shown on the Mission HUD, allowing us to approximate the points earned. The HUD Destruction Meter and HUD Damage Indicator are at least fun and more concerned.
I’m currently use HUD Progress Meter, HUD Enemy Health Indicator and HUD Damage Indicator. The HUD Pecking Order Revealer is good for farming bonus points, but I don’t care about it that much.
