Adds 2 new shield types:
- **Improvised Shield.** Made out of 10 iron sheets and 2 sticky tape
pieces. Weaker then buckler shield and breaks after 2 gunshots or 4
baton hits, but has a 50% (BASE FOR ALL OTHER SHIELDS) blocking chance
instead of 30% that buckler has. Bulky
- **Ballistic Shield.** Printed at Security Techfab for a lot of
titanium after getting weapon research. Strong against projectiles, but
weaker than riot shield against melee. Bulky

Both of these shields break, and both of them are their own subtype. As
such you can still only craft strobe shield with a riot shield.
## Why It's Good For The Game

The sprites of shields were very ancient and extremely flat, this gives
them a more refreshed look.

Ballistic Shield is added because Riot Shield was weakened against
projectiles, Ballistic Shield gives the crew a way to get access to
protection against projectiles at some point in the round.
Improvised Shield adds a second improvised shield in the game (after
Buckler Shield). It's balanced by being weaker than Buckler, but higher
block chance, this adds an interesting choice for players on which
shield to craft.
## Changelog
:cl:
add: Adds 2 new shields to the game! Ballistic Shield - researched by
Science, and Improvised Shield - made out of iron and sticky tape
image: Riot, Strobe, Telescopic, Energy shields got new less flat
sprites!
