Minefield - You move, you explode (just kidding on this one)
I liked it, why "joke"?
Because every weapon has knockback now, so whoever goes first would get a huge advantage. If the knockback was put back to its previous level, it could work
Ice-Land - You never overheat, heat weapons do half damage
I only use heat weapons, this will ruin my game and it is totally random
That's the point, to make things a bit more random, so no matter how good you build your mech, there will be stages you are bad at.
On the flip side, there would also be levels that enhance your mech design.
e.g. if you go up against a mech 5 times you level on the desert stage, you could win, because the desert heat enhances you heat attacks.
Zero-G/Space - Knockback and jumping distances are double (maybe walking distance too)
Anyone else have any ideas for stages?
