Just created a PR for the spikes. Slows infantry, and makes them loose 1h/s, and cav still loose what they did before. Also increases pierce resistance to 50, because arrows and stuff probably wouldn't hurt it that much, it would only really add to it
The game 0.A.D. is totally amazing. Absolutely loving it. I played it 5 hours straight after install it. Unbelievable! Totally addictive. It's like advanced version of AOE series.
