I'm still new to CS2D and I'm not sure whether the following features are available in CS2D.
If yes, I hope to know more about the feature; if no, is it possible to introduce it by lua or even in the next version of CS2D?
1. Damage done by explosion---C4 or tile effect---decreases with distance. e.g. if the explosion range of C4 is 1000, it becomes lethal within 900 (exact no. tentative), causing various damage from 900 to 1500 and does nothing beyond 1500.
2. (there was a post earlier discussing about that) Bullets fired becomes more scattered for holding the fire button without release.
(if you have a PSP with CFW, have a try on a game called "CSPSP". The scattered fire feature in that game is what I'm thinking of.)
3. Bullet damage decreases with distance (similar to #1)
4. It takes more damage to get hit from the back than to get hit from the side which, in turn, more damage than at the front. e.g. it may take 10 damage at the front by certain firearm, and that gun causes 15 damage on your side and 20 at your back---again, exact damage is negotiable.
5. Reaction time of turret after upgrading becomes longer (for about 300-400 ms per level?) because having one more turret barrow should increase its weight.
